89-445: Roger and Rover are the two main characters. Rover the dog is frequently kidnapped by robots. The player, Roger the owner, must enter robot territory and get him back, hence the name "Rescue Rover". Each level starts with Roger climbing up a ladder set into the floor, and the player completes the level by arriving back at this ladder with Rover - at which point Roger climbs down with Rover. Gameplay involves getting Rover out repeatedly in

178-408: A side-scrolling format. Later notable side-scrolling run and gun shooters include Namco's Rolling Thunder (1986), which added cover mechanics to the formula, and Data East's RoboCop (1988). In 1987, Konami created Contra , a side-scrolling coin-op arcade game, and later a NES game, that was particularly acclaimed for its multi-directional aiming and two-player cooperative gameplay. By

267-431: A sub-genre of action games . There is no consensus as to which design elements compose a shoot 'em up; some restrict the definition to games featuring spacecraft and certain types of character movement, while others allow a broader definition including characters on foot and a variety of perspectives. The genre's roots can be traced back to earlier shooting games , including target shooting electro-mechanical games of

356-435: A video game . An individual involved with the development of game levels is a level designer or mapper. In some cases, the developer of a video game includes built-in level editing tools; for example, a track editor for a racing game. Other times they may release an official level editor for the game as a separate application. Sometimes players of the game develop fan-made level editors. Developing level editors will allow

445-471: A "shmup" or "STG" (the common Japanese abbreviation for "shooting games"), is a game in which the protagonist combats a large number of enemies by shooting at them while dodging their fire. The controlling player must rely primarily on reaction times to succeed. Beyond this, critics differ on exactly which design elements constitute a shoot 'em up. Some restrict the genre to games featuring some kind of craft, using fixed or scrolling movement. Others widen

534-401: A black background. It had a more interactive style of play than earlier target shooting games, with multiple enemies who responded to the player-controlled cannon's movement and fired back at the player. The game ended when the player was killed by the enemies. While earlier shooting games allowed the player to shoot at targets, Space Invaders was the first where multiple enemies fired back at

623-590: A cult following with the gamers, a factor which led to creation of a sequel. In a 2008 IGN reader poll about their favorite early id game, Rescue Rover received one vote. Level (video games) In video games , a level (also referred to as a map , mission , stage , course , or round in some older games) is any space available to the player during the course of completion of an objective. Video game levels generally have progressively increasing difficulty to appeal to players with different skill levels. Each level may present new concepts and challenges to keep

712-415: A different environment. Level designers sometimes make hidden rooms and areas that usually require more effort for the player to reach or to notice. These usually give some additional rewards, such as ammo or powerups. They serve to induce players to explore. Sometimes, they serve as easter eggs , containing messages such as the level designers' names or pictures, or political or humorous messages. One of

801-554: A different person or team. The level design process may be iterated several times before achieving the desired outcome. Level designers and concept artists may also be required to provide a pre-rendered map of the level (or entire game world) for the player. Level design is necessary for two primary purposes: providing players with a goal and providing players with enjoyable play experience. Good level design strives to produce quality gameplay, provide an immersive experience, and sometimes, especially in story-based games, to advance

890-505: A game than simply adding new levels, a software development kit (SDK) is sometimes needed. In the early years of video gaming, some games came with a utility called a "construction set". This was similar in many ways to a level editor. Some games used them to make extra levels, whereas others (like the Shoot-'Em-Up Construction Kit ) used them as a means to develop a game rather than be a game in itself. Maps' design can significantly impact

979-406: A level system of ascending difficulty as opposed to progression of storyline. An example of the former approach is the arcade shoot 'em up game Space Invaders (1978), where each level looks the same, repeating endlessly until the player loses all their lives . An example of the latter approach is the arcade platform game Donkey Kong (1981), which uses multiple distinct levels to progress

1068-407: A level. Sometimes, professional 3D editing software , such as 3D Studio Max , Blender , AutoCAD , Lightwave , Maya , Softimage XSI or Grome is used, usually customized with a special plugin developed for the specific game. A level editor (also known as a map , campaign or scenario editor ) is a game development tool used to design levels, maps, campaigns and virtual worlds for

1157-457: A map and these steps may vary dramatically across the many different game genres that exist as of the 2020s. General steps include: The first level of the game is usually designed to get players to explore the mechanics of the game, notably in World 1-1 of Super Mario Bros. Cut scenes may be triggered by events in a level, but require distinctly different skills, and may be produced by

1246-450: A modern game typically starts with concept art, sketches, renderings, and physical models. Once completed, these concepts transform into extensive documentation, environment modeling, and the placing of game specific entities (actors), usually with the aid of a level editor. A level editor may be distributed as a complete stand-alone package, at times, rivaling commercial 3D modelling software. There are various steps involved in laying out

1335-567: A more successful attempt to incorporate a 3D perspective into shooter games; Tempest went on to influence several later rail shooters. Sega's Zaxxon (1981) introduced isometric video game graphics to the genre. The term "shmup" is believed to have been coined in 1985 by the British Commodore 64 magazine Zzap!64 . In the July 1985 issue, the term was used by the editor Chris Anderson and reviewer Julian Rignall . 1985 saw

1424-404: A player's interest high. In games with linear progression, levels are areas of a larger world, such as Green Hill Zone . Games may also feature interconnected levels, representing locations. Although the challenge in a game is often to defeat some sort of character, levels are sometimes designed with a movement challenge, such as a jumping puzzle, a form of obstacle course . Players must judge

1513-417: A rail shooter released in 1985, broke new ground graphically and its wide variety of settings across multiple levels gave players more to aim for than high scores. In 1986, Arsys Software released WiBArm , a shooter that switched between a 2D side-scrolling view in outdoor areas to a fully 3D polygonal third-person perspective inside buildings, while bosses were fought in an arena-style 2D battle, with

1602-468: A set of increasingly difficult levels , by moving objects around in a grid to open up a path to get to the dog and then bring it back out. There are four different types of robot in the game, each with different behaviour. One type shoots Roger if he stands in front of it, but doesn't move, another type runs around and shoots Roger if he is seen, another type chases Roger around, and the last type runs around and kills Roger if it runs into him. To get to Rover,

1691-541: A shoot 'em up, as opposed to an action-adventure game . The success of Commando and Ikari Warriors led to run and gun games becoming the dominant style of shoot 'em up during the late 1980s to early 1990s, with the term "shoot 'em up" itself becoming synonymous with "run and gun" during this period. Konami 's Green Beret (1985), known as Rush'n Attack in North America, adapted the Commando formula to

1780-540: A specific spot where they do not have to move to gain experience , because monsters are constantly spawned but can be easily and immediately killed. In multiplayer maps, a player may be able to reach areas of the map designed to be inaccessible; for example, reaching an advantageous rooftop position and camping other players. A player might be able to fall out-of-bounds of a map where other players cannot reach them. Invisible walls are cited to be level design bugs, and might be "left-over geometry" from an earlier version of

1869-412: A storyline; as Mario (originally called Jumpman) tries to rescue Pauline from Donkey Kong , each level ends with Kong fleeing with Pauline and then Mario having to complete a different level each time, until he finally confronts Kong. 1983's Lode Runner was one of the first titles to ship with a level editor. Its designer, Doug Smith , reputedly paid neighborhood children to design levels for

1958-526: A straight line at constant speeds. The player's character can collect " power-ups " which may afford the character's greater protection, an " extra life ", health, shield, or upgraded weaponry. Different weapons are often suited to different enemies, but these games seldom keep track of ammunition. As such, players tend to fire indiscriminately, and their weapons only damage legitimate targets. Shoot 'em ups are categorized by their design elements, particularly viewpoint and movement: Fixed shooters restrict

2047-576: A third-person view, and featured the use of force feedback , where the joystick vibrates. Over the course of the 1990s, a new subgenre of shooters evolved, known as " danmaku ( 弾幕 , "barrage") in Japan, and often referred to as "bullet hell" or "manic shooters" in English-speaking regions. These games are characterized by high numbers of enemy projectiles, often in complex "curtain fire" patterns, as well as collision boxes that are smaller than

2136-458: A total high data throughput can eliminate the need for any loading tunnels in a seamless world game. A level designer is a game designer who makes environments and scenarios using a level editor and other tools. Level designers will usually work on a level from pre-production to completion – working with both incomplete and complete versions of the game. Video game programmers usually produce level editors and design tools for

2225-487: A vehicle or spacecraft under constant attack. Thus, the player's goal is to shoot as quickly as possible at anything that moves or threatens them to reach the end of the level, usually with a boss battle . In some games, the player's character can withstand some damage or a single hit will result in their destruction. The main skills required in shoot 'em ups are fast reactions and memorising enemy attack patterns. Some games feature overwhelming numbers of enemy projectiles and

2314-555: A wrap-around game world, unlike most later games in the genre. The scrolling helped remove design limitations associated with the screen, and it also featured a minimap radar. Scramble , released by Konami in early 1981, had continuous scrolling in a single direction and was the first side-scrolling shooter with multiple distinct levels . In the early 1980s, Japanese arcade developers began moving away from space shooters towards character action games , whereas American arcade developers continued to focus on space shooters during

2403-482: Is a subgenre of shooters in which the screen becomes crowded with complex "curtain fire" enemy patterns. It is also characterized by collision boxes that are smaller than the sprites themselves, to accommodate maneuvering through these crowded firing patterns. This style of game, also known as "manic shooters" or "maniac shooters", originated in the mid-1990s as an offshoot of scrolling shooters. The DonPachi and Touhou Project series are early titles establishing

2492-470: Is most often seen in platformers. Lighting and illumination, as well as distinctly-coloured objects, are often used to unambiguously guide the player towards the correct path. Similarly, clearly marked choke-points can be introduced. Another method is strategic placement of obstacles and aesthetic environment props that direct the player's attention to "clear" paths instead. This is often used in closed, "stuffed" environments. Levels may be designed to force

2581-477: Is notable for using a traditional fantasy setting in contrast to most shoot 'em up games filled with science fiction motifs. R-Type , an acclaimed side-scrolling shoot 'em up, was released in 1987 by Irem , employing slower paced scrolling than usual, with difficult, claustrophobic levels calling for methodical strategies. 1990's Raiden was the beginning of another acclaimed and enduring series to emerge from this period. Run and gun games became popular in

2670-864: Is still a single axis of motion, making these a subset of fixed shooters. Rail shooters limit the player to moving around the screen while following a specific route; these games often feature an "into the screen" viewpoint, with which the action is seen from behind the player character , and moves "into the screen", while the player retains control over dodging. Examples include Space Harrier (1985), Captain Skyhawk (1990), Starblade (1991), Star Fox (1993), Star Wars: Rebel Assault (1993), Panzer Dragoon (1995), and Sin and Punishment (2000). Rail shooters that use light guns are called light gun shooters , such as Operation Wolf (1987), Lethal Enforcers (1992), Virtua Cop (1994), Point Blank (1994), Time Crisis (1995), The House of

2759-515: The Geometry Wars series, Space Invaders Extreme , Super Stardust HD , and Resogun . The concept of shooting games existed before video games , dating back to shooting gallery carnival games in the late 19th century and target sports such as archery , bowling and darts . Mechanical target shooting games first appeared in England 's amusement arcades around the turn of

2848-575: The Front Line tank shooter format with unique rotary joystick controls, which they later combined with Commando -inspired run and gun gameplay to develop Ikari Warriors (1986), which further popularized run and gun shooters. Ikari Warriors also drew inspiration from the action film Rambo: First Blood Part II (1985), which it was originally intended to be an adaptation of. Contemporary critics considered military themes and protagonists similar to Rambo or Schwarzenegger prerequisites for

2937-466: The Xbox 360 , PlayStation 3 and Wii online services, while in Japan arcade shoot 'em ups retain a deep-rooted niche popularity. Geometry Wars: Retro Evolved was released on Xbox Live Arcade in 2005 and in particular stood out from the various re-releases and casual games available on the service. The PC has also seen its share of dōjin shoot 'em ups like Crimzon Clover , Jamestown: Legend of

3026-430: The vertical scrolling format later popularized by Capcom 's Commando (1985), which established the standard formula used by later run and gun games. Sega's Ninja Princess (1985), which released slightly before Commando , was a run and gun game that was distinctive for its feudal Japan setting and female ninja protagonist who throws shuriken and knives. SNK 's TNK III , released later in 1985, combined

3115-498: The 1980s to early 1990s, diversifying into a variety of subgenres such as scrolling shooters, run and gun games and rail shooters. In the mid-1990s, shoot 'em ups became a niche genre based on design conventions established in the 1980s, and increasingly catered to specialist enthusiasts, particularly in Japan. " Bullet hell " games are a subgenre of shooters that features overwhelming numbers of enemy projectiles , often in visually impressive formations. A "shoot 'em up", also known as

3204-530: The 20th century, before appearing in America by the 1920s. Shooting gallery games eventually evolved into more sophisticated target shooting electro-mechanical games (EM games) such as Sega 's influential Periscope (1965). Shooting video games have roots in EM shooting games. Video game journalist Brian Ashcraft argues the early mainframe game Spacewar! (1962) was the first shoot 'em up video game. It

3293-511: The Dead (1996) and Elemental Gearbolt (1997). Light-gun games that are "on rails" are usually not considered to be in the shoot-em-up category, but rather their own first-person light-gun shooter category. Cute 'em ups feature brightly colored graphics depicting surreal settings and enemies. Cute 'em ups tend to have unusual, oftentimes completely bizarre opponents for the player to fight, with Twinbee and Fantasy Zone first pioneering

3382-522: The Haunted Mansion . Rescue Rover was released in 1991. In 1997, it was included in an anthology of all id's games to date. David Kushner , in Masters of Doom , called it "a clever maze game" and cited it as an example of an emerging trend in id's games: darkly humorous violence. Travis Fahs of IGN wrote that despite the title was less impressive compared to other id's games, Rover had

3471-634: The closure of Toaplan, the following year, a number of studios formed from former Toaplan staff that would continue to develop this style, including Cave (formed by Batsugun's main creator Tsuneki Ikeda) who released 1995's seminal DonPachi , and Takumi, who would develop the GigaWing series. Bullet hell games marked another point where the shooter genre began to cater to more dedicated players. Games such as Gradius had been more difficult than Space Invaders or Xevious , but bullet hell games were yet more inward-looking and aimed at dedicated fans of

3560-518: The computer hardware sufficient time to load the assets for the next area. The player's speed may be reduced, while story cues are presented to draw the player's attention. The player may be required to enter areas in which their view of the world is plausibly restricted, sometimes referred to as "loading tunnels". With newer consoles, such as the PlayStation 5 and Xbox Series X and Series S , special SSD arrays alongside software libraries that have

3649-428: The computer or console's memory as the player approaches the edge of one level and the start of a new one. This can effectively make the transition from one level to another level appear to be seamless and avoid the use of loading screens. This is known as level streaming or in-game streaming, and is often used for open world games to give the perception of a fully-interconnected space. There are often tricks used to give

3738-418: The current), laser projectors, teleporters and force doors (which need an access card in order to be opened). Rescue Rover had its programming origins in an aborted Super Mario Bros. 3 port that id proposed to Nintendo six months earlier in 1990. Though Nintendo declined, the advances that it made in that demo aided development of their later projects, including Commander Keen and Dangerous Dave in

3827-440: The designers to use. This eliminates the need for designers to access or modify game code . As opposed to the level editing tools sometimes available to the community, level designers often work with placeholders and prototypes aiming for level consistency and clear layout before required artwork is produced by game artists. Many level designers have skills as both a visual artist and game designer , although in recent years

3916-426: The distance between platforms or ledges and safely jump between them to reach the next area. These puzzles can slow the momentum down for players of fast action games ; the first Half-Life 's penultimate chapter, "Interloper", featured multiple moving platforms high in the air with enemies firing at the player from all sides. Level design or environment design , is a discipline of game development involving

4005-629: The early 1980s, up until the end of the arcade golden age. According to Eugene Jarvis , American developers were greatly influenced by Japanese space shooters but took the genre in a different direction from the "more deterministic, scripted, pattern-type" gameplay of Japanese games, towards a more "programmer-centric design culture, emphasizing algorithmic generation of backgrounds and enemy dispatch" and "an emphasis on random-event generation, particle-effect explosions and physics" as seen in arcade games such as his own Defender and Robotron: 2084 (1982) as well as Atari's Asteroids (1979). Robotron: 2084

4094-400: The early 1990s and the popularity of 16-bit consoles , the scrolling shooter genre was overcrowded, with developers struggling to make their games stand out, with exceptions such as the inventive Gunstar Heroes (1993) by Treasure . Sega's pseudo-3D rail shooter Buck Rogers: Planet of Zoom demonstrated the potential of 3D shoot 'em up gameplay in 1982. Sega's Space Harrier ,

4183-503: The emergence of one of Sega's forefront series with its game Fantasy Zone . The game received acclaim for its surreal graphics and setting and the protagonist, Opa-Opa, was for a time considered Sega's mascot . The game borrowed Defender's device of allowing the player to control the direction of flight and along with the earlier TwinBee (1985), is an early archetype of the "cute 'em up" subgenre. In 1986, Taito released KiKi KaiKai , an overhead multi-directional shooter. The game

4272-494: The first games to popularize twin-stick controls was Robotron: 2084 (1982). Space shooters are a thematic variant of involving spacecraft in outer space . Following the success of Space Invaders , space shooters were the dominant subgenre during the late 1970s to early 1980s. These games can overlap with other subgenres as well as space combat games . Tube shooters feature craft flying through an abstract tube, such as Tempest (1981) and Gyruss (1983). There

4361-483: The first games with a 3D engine to feature hidden features was Wolfenstein 3D , where certain walls could be pushed to reveal hidden passages. Sometimes, a whole level may be designed as a secret level. A bonus stage (also known as a bonus level or bonus round) is a special level within a video game designed to reward the player or players, and typically allows the player to collect extra points or power-ups . Bonus stage either have no enemies or hazards, or replace

4450-415: The game because of their limited replay value. A minigame (also spelled mini-game or mini game, sometimes called a subgame or microgame) is a short video game often contained within another video game, and sometimes in application software or on a display of any form of hardware. A minigame contains different gameplay elements than the main game, may be optional, and is often smaller or more simplistic than

4539-407: The game creator to use the same load- and rendering routines as the game itself, and may make it easier and more pleasant to create levels. Developers of FOSS -games may argue that a game is not complete until other users easily can add new levels. One of the first 3D games which became popular partially due to level editors and fan-made maps, other game addons, and other works related to the game,

4628-457: The game featuring a variety of weapons and equipment. In 1987, Square's 3-D WorldRunner was an early stereoscopic 3-D shooter played from a third-person perspective, followed later that year by its sequel JJ , and the following year by Space Harrier 3-D which used the SegaScope 3-D shutter glasses . That same year, Sega's Thunder Blade switched between both a top-down view and

4717-428: The game in which it is contained. Minigames are sometimes also offered separately for free to promote the main game. Some minigames can also be bonus stages or secret levels. They are distinguishable from levels in that a level is an environment bound to a set of mechanics and rules that all defines all other normal levels in a game, whereas a minigame can use different rules and playstyles but may not necessarily be set in

4806-479: The game interface itself. 3D first-person shooters Doom (1993) and Doom II (1994) were two of the first games to attract focused game modding activity, and many WAD level files were made for them. One of the reasons was a clear separation between the level files and game engine itself. Half-Life , Quake 3 , and many other games have notable mapping tools and communities focusing on user-generated content . Level design for each individual level in

4895-454: The game. The same year, the multiplayer dungeon crawl Dandy was released, and it also shipped with a level editor which was documented in the manual. ZZT (1991) is a later game with user-accessible mapping and scripting. A game genre that required significant amounts of time to design areas were text-based games, such as MUDs . Often, promoted users were assigned to make new paths, new rooms, new equipment, and new actions, often using

4984-597: The gameplay. For example, the gameplay may be shifted towards a platformer (by careful placement of platforms) or a puzzle game (by extensive use of buttons, keys, and doors). Some FPS maps may be designed to prevent sniping by not including any long hallways, while other maps may allow for a mix of sniping and closer combat. Gimmick maps are sometimes developed to explore selected features of gameplay, such as sniping or fist fighting. While they are briefly useful to level designers and interesting to experienced players, they are usually not included in final list of levels of

5073-431: The genre looking for greater challenges. While shooter games featuring protagonists on foot largely moved to 3D-based genres, popular, long-running series such as Contra and Metal Slug continued to receive new sequels. Rail shooters have rarely been released in the new millennium, with only Rez and Panzer Dragoon Orta achieving cult recognition. In the early 2000s, the genre achieved recognition through

5162-543: The level or an object's improperly aligned "collision box". In some cases, specific mapping tools can be designed to automatically detect problems such as falling "outside" a level, and reaching "stuck" areas. Careful level designers run these tools as the last step before releasing a new version of a level. In most cases, the best way to improve a map is by playtesting it with experienced players, and allowing them to try to exploit any problems. Shoot %27em up Shoot 'em ups (also known as shmups or STGs ) are

5251-459: The making of video game levels—locales, stages or missions. This is commonly done using a level editor, a game development software designed for building levels; however, some games feature built-in level editing tools. In the early days of video games (1970s–2000s), a single programmer would develop the maps and layouts for a game, and a discipline or profession dedicated solely to level design did not exist. Early games often featured

5340-420: The mid-1980s. These games feature characters on foot, rather than spacecraft, and often have military themes. The origins of this type of shooter go back to Sheriff by Nintendo , released in 1979. SNK 's Sasuke vs. Commander (1980), which had relatively detailed background graphics for its time, pit a samurai against a horde of ninjas , along with boss fights . Taito's Front Line (1982) introduced

5429-411: The mid-20th-century, but did not receive a video game release until Spacewar! (1962). The shoot 'em up genre was established by the hit arcade game Space Invaders , which popularised and set the general template for the genre in 1978, and has spawned many clones. The genre was then further developed by arcade hits such as Asteroids and Galaxian in 1979. Shoot 'em ups were popular throughout

5518-432: The mobile game Space Impact , which is considered one of the important games in the history of mobile games . Treasure's shoot 'em up, Radiant Silvergun (1998), introduced an element of narrative to the genre. It was critically acclaimed for its refined design, though it was not released outside Japan and remains a much sought-after collector's item. Its successor Ikaruga (2001) featured improved graphics and

5607-534: The normal penalties for being struck by enemies or hazards with simply being thrown out of the bonus stage. Many bonus stages need to be activated or discovered in some manner, or certain conditions must be satisfied to access them. Otherwise, they appear after the player has completed a certain number of regular stages. There are many map bugs that level designers try to avoid, but sometimes go unnoticed for some time. A player might get stuck in map geometry with no way to escape or to die. A player might be able to find

5696-456: The player against multiple enemies descending from the top of the screen at a constantly increasing speed. Nishikado conceived the game by combining elements of Breakout (1976) with those of earlier target shooting games, and simple alien creatures inspired by H. G. Wells ' The War of the Worlds . The hardware was unable to render the movement of aircraft, so the game was set in space, with

5785-401: The player and enemies to a single screen, and the player primarily moves along a single axis, such as back and forth along the bottom of the screen. Examples include Space Invaders (1978), Galaxian (1979), Phoenix (1980), and Galaga (1981). In Pooyan (1982), the fixed axis of movement is vertical, along the right side of the screen. In Centipede (1980) and Gorf (1981),

5874-524: The player completed the level, the next level would be loaded. The player would be presented with a loading screen while the game loaded level information from storage. With more advanced computing hardware with faster input/output data transfer rates, such as optical drives, hard disk drives (HDDs), solid-state drives (SSDs), and larger amounts of memory, game developers have been able to take advantage of continuously loading new level assets – models, textures, and audio – into

5963-574: The player has to memorise their patterns to survive. These games belong to one of the fastest-paced video game genres . Large numbers of enemy characters programmed to behave in an easily predictable manner are typically featured. These enemies may behave in a certain way dependent on their type, or attack in formations that the player can learn to predict. The basic gameplay tends to be straightforward with many varieties of weapons. Shoot 'em ups rarely have realistic physics. Characters can instantly change direction with no inertia , and projectiles move in

6052-491: The player in a trance-like state. In trance shooters, enemy patterns usually have randomized elements, forcing the player to rely on reflexes rather than pattern memorization. Games of this type usually feature colorful, abstract visuals, and electronic music (often techno music ). Jeff Minter is commonly credited with originating the style with Tempest 2000 (1994) and subsequent games including Space Giraffe , Gridrunner++ , and Polybius (2017). Other examples include

6141-416: The player must normally avoid, trap or destroy them. There are various items which Roger can push around in the world: crates (which float on water), mirror blocks (which reflect lasers at an angle), star pearls and anti-gravity carts. Other items in the areas are grated floors (which robots cannot travel on), glowing floors (which Roger cannot travel on), water (including moving water in which crates float with

6230-480: The player primarily moves left and right along the bottom, but several inches of vertical motion are also allowed within an invisible box. Multidirectional shooters allow 360-degree movement where the protagonist may rotate and move in any direction such as Asteroids (1979) and Mad Planets (1983). Multidirectional shooters with one joystick for movement and one joystick for firing in any direction independent of movement are called twin-stick shooters . One of

6319-415: The player's flying vehicle moving forward, at a fixed rate, through an environment. Examples are Scramble (1981), Xevious (1982), Gradius (1986), Darius (1987), R-Type (1987), Einhänder (1997). In contrast, Defender (1981) allows the player to move left or right at will. Run and gun games have protagonists that move through the world on foot and shoot attackers. Examples include

6408-549: The player. It also introduced the idea of giving the player multiple lives and popularized the concept of achieving a high score . With these elements, Space Invaders set the general template for the shoot 'em up genre. It became one of the most widely cloned shooting games, spawning more than 100 imitators with only the most minor differences (if any) from the original. Most shooting games released since then have followed its "multiple life, progressively difficult level " paradigm, according to Eugene Jarvis . Following

6497-439: The players to explore the map and advance. Most Real-Time Strategy maps give each player a starting base, but will have resource distribution and terrain features designed to draw players out of their base and engage each other. Teamplay maps can provide noticeable advantages to one team over another, when designed poorly. Commonly on older hardware, most games would load a single level and all of its assets at one time, and when

6586-548: The principle of bullet hells. A bullet heaven or reverse bullet hell is a subgenre characterized by the player character collecting or unlocking abilities and attacks whose visuals overlap and clutter the game screen as the game progresses. They also share a feature of many enemy characters, commonly called "hordes", walking toward the player from off-screen. This genre is generally attributed to Vampire Survivors , released in 2022. A small subgenre of shooter games that emphasizes chaotic, reflex-based gameplay designed to put

6675-416: The release of Konami's Gradius , which gave the player greater control over the choice of weaponry, thus introducing another element of strategy. The game also introduced the need for the player to memorise levels in order to achieve any measure of success. Gradius , with its iconic protagonist, defined the side-scrolling shoot 'em up and spawned a series spanning several sequels. The following year saw

6764-505: The responsibility for visual-, structural- and gameplay-related tasks has been increasingly divided among several specialists. A wide variety of tools may be used by someone designing and making a level. Although it is faster to design models and textures with general-purpose multimedia development tools, games usually require the data to be in a unique format suited for that game's engine . For this, specific compilers and converters of models, textures, and audio data may be required to lay out

6853-423: The scope to include games featuring such protagonists as robots or humans on foot, as well as including games featuring "on-rails" (or "into the screen") and "run and gun" movement. Mark Wolf restricts the definition to games featuring multiple antagonists ("'em" being short for "them"), calling games featuring one-on-one shooting "combat games". Formerly, critics described any game where the primary design element

6942-477: The sprites themselves, allowing the player to fit between the narrow gaps in enemy fire. Bullet hell games were first popularized in Japanese arcades during a time when 3D games and fighting games were eclipsing other games. The flashy firing patterns were intended to grab players attention. Toaplan 's Batsugun (1993) is often considered a pivotal point in the development of this subgenre. After

7031-424: The storyline. Levels are generally constructed with flow control in mind; that is, directing the player towards the goal of the level and preventing confusion and idling. This can be accomplished by various means. Often the level layouts feature power-ups and items positioned so that collecting them inevitably makes the player move in the correct direction. This is one of the basic player direction techniques and

7120-612: The subgenre, along with Parodius , Cotton , and Harmful Park being additional key games. Some cute 'em ups may employ overtly sexual characters and innuendo. Vertically scrolling shooters present the action from above and scroll up (or occasionally down) the screen. Horizontally scrolling shooters usually present a side-on view and scroll left to right (or less often, right to left). Isometrically scrolling shooters or isometric shooters , such as Sega 's Zaxxon (1982), use an isometric point of view . A popular implementation style of scrolling shooters has

7209-550: The success of Space Invaders , shoot 'em ups became the dominant genre for much of the golden age of arcade video games , from the late 1970s up until the early 1980s, particularly the "space shooter" subgenre. In 1979, Namco 's Galaxian —"the granddaddy of all top-down shooters", according to IGN—was released. Its use of colour graphics and individualised antagonists were considered "strong evolutionary concepts" among space ship games. In 1981 Gorf brought joystick control and (limited) vertical as well as horizontal movement to

7298-472: The vertically scrolling, overhead view games Front Line (1982), Commando (1985), and Ikari Warriors (1986). Side-scrolling run and gun games often combine elements from platform games , such as the ability to jump: Contra (1987), Metal Slug (1996) and Cuphead (2017). Run and gun games may also use isometric viewpoints and may have multidirectional movement. Bullet hell ( 弾幕 , danmaku , literally "barrage" or "bullet curtain")

7387-545: The vertically-oriented fixed-shooter genre, while Space Invaders and Galaxian have only horizontal movement controlled by a pair of buttons. Atari 's Asteroids (1979) was a hit multi-directional shooter, taking from Spacewar! the ability for the player's ship to roam the entire screen and to rotate, move and shoot in any direction. The Space Invaders format evolved into the vertical scrolling shooter sub-genre. SNK 's debut shoot 'em up Ozma Wars (1979) featured vertical scrolling backgrounds and enemies, and it

7476-508: Was Doom . The development of various third-party editors led to the formation of an online community trading fan-made maps. A level editor is often limited to designing levels for only a certain game engine . Developing a level editor takes a lot of time; it is more time- and cost-efficient to release multiple games using the same engine instead of developing a new engine and level editor for each game. As level editors generally allow for limited game-development work, to make larger changes to

7565-530: Was again acclaimed as one of the best games in the genre. Both Radiant Silvergun and Ikaruga were later released on Xbox Live Arcade . The Touhou Project series spans 26 years and 30 games as of 2022 and was listed in the Guinness World Records in October 2010 for being the "most prolific fan-made shooter series". The genre has undergone something of a resurgence with the release of

7654-421: Was an influential game in the multi-directional shooter subgenre. Some games experimented with pseudo-3D perspectives at the time. Nintendo 's attempt at the genre, Radar Scope (1980), borrowed heavily from Space Invaders and Galaxian , but added a three-dimensional third-person perspective; the game was a commercial failure, however. Atari's Tempest (1981) was one of the earliest tube shooters and

7743-506: Was developed at the Massachusetts Institute of Technology in 1961, for the developers' amusement, and presents a space battle between two craft. It was remade four times as an arcade video game in the 1970s. Space Invaders (1978) is most frequently cited as the "first" or "original" in the genre. A seminal game created by Tomohiro Nishikado of Japan's Taito , it led to proliferation of shooter games. It pitted

7832-404: Was shooting as a "shoot 'em up", but later shoot 'em ups became a specific, inward-looking genre based on design conventions established in those shooting games of the 1980s. Shoot 'em ups are a subgenre of action game . These games are usually viewed from a top-down or side-view perspective , and players must use ranged weapons to take action at a distance. The player's avatar is typically

7921-546: Was the first action game to feature a supply of energy, similar to hit points . Namco's Xevious , released in 1982, was one of the first and most influential vertical scrolling shooters. Xevious is also the first to convincingly portray dithered/shaded organic landscapes as opposed to blocks-in-space or wireframe obstacles. Side-scrolling shoot 'em ups emerged in the early 1980s. Defender , introduced by Williams Electronics in late 1980 and entering production in early 1981, allowed side-scrolling in both directions in
