97-634: Team Fortress 2 ( TF2 ) is a multiplayer first-person shooter game developed and published by Valve Corporation in 2007. It is the sequel to the 1996 Team Fortress mod for Quake and its 1999 remake, Team Fortress Classic . The game was released in October 2007 as part of The Orange Box for Microsoft Windows and the Xbox 360 , and was ported to the PlayStation 3 in December 2007. It

194-466: A wide area network (a common example being the Internet). Unlike local multiplayer, players playing online multiplayer are not restricted to the same local network. This allows players to interact with others from a much greater distance. Playing multiplayer online offers the benefits of distance, but it also comes with its own unique challenges. Gamers refer to latency using the term " ping ", after

291-399: A 1960s spy film aesthetic. Team Fortress 2 has received critical acclaim for its art direction, gameplay, humor, and use of character in a wholly multiplayer game, and since its release has been referred to as one of the greatest video games ever created . The game continues to receive official Valve server support as of 2024, in addition to new content being released on a seasonal basis in

388-478: A LAN. This involves multiple devices using one local network to play together. Networked multiplayer games on LAN eliminate common problems faced when playing online such as lag and anonymity. Games played on a LAN network are the focus of LAN parties . While local co-op and LAN parties still take place, there has been a decrease in both due to an increasing number of players and games utilizing online multiplayer gaming. Online multiplayer games connect players over

485-458: A blog post was made on the official Team Fortress 2 website, saying that a new "update-sized" update was coming to the game (the last major update had taken place in October 2017). The post included a call to Steam Workshop creators to submit content which had a chance to be selected for inclusion, with a submission deadline of May 1. The announcement was met with an overwhelmingly positive reception, causing Valve to temper expectations by amending

582-445: A combat-based objective. Players can choose to play as one of nine character classes in these teams, each with its own unique strengths, weaknesses, and weapon sets. In order to accomplish objectives efficiently, a balance of these classes is required due to how these strengths and weaknesses interact with each other in a team-based environment. Although the abilities of a number of classes changed from earlier Team Fortress incarnations,

679-412: A command hierarchy with a Commander class, parachute drops over enemy territory, and networked voice communication. The Commander class played similarly to a real-time strategy game; the player viewed the game from a bird's-eye perspective and issued orders to players and AI-controlled soldiers. The Commander class was eventually abandoned because players would simply disobey the orders. Team Fortress 2

776-608: A contribution site; many of the most popular are added to the game. This approach has subsequently created the basis for the Steam Workshop functionality of the software client. In one case, more than fifty users from the content-creation community worked with Valve to release an official content update in May 2013, with all of the content generated by these players. Valve reported that as of June 2013, over $ 10 million has been paid back to over 400 persons who have contributed content to

873-451: A drastically different way, with different mechanics, a different type of objective, or both. Examples of games with strong asymmetry include Dead by Daylight , Evolve , and Left 4 Dead . Asynchronous multiplayer is a form of multiplayer gameplay where players do not have to be playing at the same time. This form of multiplayer game has its origins in play-by-mail games , where players would send their moves through postal mail to

970-501: A factor of twelve. Since early 2020, Team Fortress 2 has seen quantities of bot accounts entering Valve's casual matchmaking servers. Though bot accounts had been an issue in Team Fortress 2 for some time prior to this, multiple sources began to report a spike in activity for these bot accounts. The activities of these bots have included forcibly crashing servers, spamming obscenities and copypastas in text chats or audio in

1067-434: A finite number of tries before the game ends with a game over . Sometimes the euphemisms chance , try , rest and continue are used, particularly in all-ages games, to avoid the morbid insinuation of losing one's "life". Generally, if the player loses all their health , they lose a life. Losing all lives usually grants the player character "game over", forcing them to either restart or stop playing. The number of lives

1164-476: A game master, who then would compile and send out results for the next turn. Play-by-mail games transitioned to electronic form as play-by-email games. Similar games were developed for bulletin board systems , such as Trade Wars , where the turn structure may not be as rigorous and allow players to take actions at any time in a persistence space alongside all other players, a concept known as sporadic play. These types of asynchronous multiplayer games waned with

1261-473: A game over can often cause players to permanently abandon a game instead of making another attempt at the level. Therefore, most modern games have completely abandoned the concept of player lives, instead simply restarting the player from the nearest checkpoint when they die, allowing them to undo or rewind their progress until such time as they are safe, as in Prince of Persia: The Sands of Time , or making saving

1358-502: A hidden value. In order to join competitive matchmaking, players must have associated their Steam account with the Steam Guard Mobile Authenticator, as well as having a Team Fortress 2 "premium account", which is unlocked by either having bought the game before it went free-to-play or by having made an in-game item purchase since. Team Fortress 2 is played in a variety of different formats, which dictate

1455-539: A life is lost when the player fails a level, but once all lives are lost, the player is prevented from continuing the game for a temporary amount of time, instead of receiving a game over that would entail total failure or require a new beginning, as lives will re-generate automatically after a number of minutes or hours. Players can either wait for lives, attempt alternate activities to recover lives (such as asking for friends online to donate lives), or purchase items that can fully replenish lives or grant unlimited lives for

1552-467: A limited time to continue playing immediately. This system works like an "energy" meter for other free-to-play games, however, lives do not deplete when a level is successfully completed, unlike energy. An extra life or a 1-up is a video game item that increments the player character's number of lives. Because there are no universal game rules, the form 1-ups take varies from game to game, but are often rare and difficult items to acquire. The use of

1649-467: A long-anticipated game that had seen years of development, and was often mentioned alongside another much-delayed game, Duke Nukem Forever . Walker said that Valve built three or four different versions of Team Fortress 2 before settling on their final design. Shortly before the release of Half-Life 2 in 2004, Valve's marketing director, Doug Lombardi, confirmed that Team Fortress 2 was still in development . Valve reintroduced Team Fortress 2 at

1746-415: A multiple-system, multiplayer mode. Turn-based games such as chess also lend themselves to single system single screen and even to a single controller. Multiple types of games allow players to use local multiplayer. The term "local co-op" or "couch co-op" refers to local multiplayer games played in a cooperative manner on the same system; these may use split-screen or some other display method. Another option

1843-439: A neutrally themed space. The bases hide exaggerated super weapons such as laser cannons, nuclear warheads , and missile launch facilities, taking the role of objectives. The maps have little visual clutter and stylized, almost impressionistic modeling, to allow enemies to be spotted more easily. The impressionistic design approach also affects textures , which are based on photos that are filtered and edited by hand, giving them

1940-471: A new main menu theme (a rendition of Taps ), as well as statues of the Soldier saluting, added to most of the official in-game maps. These statues all featured a commemorative plaque dedicated to May and lasted through the end of the month. One of these statues, appearing on the map "cp_granary", the setting of the "Meet the Soldier" short video, was made permanent in an August 21 update. On February 9, 2023,

2037-403: A number of console , and personal computer games too. Local multiplayer games played on a singular system sometimes use split screen , so each player has an individual view of the action (important in first-person shooters and in racing video games ) Nearly all multiplayer modes on beat 'em up games have a single-system option, but racing games have started to abandon split-screen in favor of

2134-589: A paid Team Fortress 2 league, with $ 42,000 in prizes for the top teams in 2017. While formalized competitive gameplay is very different from normal Team Fortress 2 , it offers an environment with a much higher level of teamwork than in public servers. Most teams use voice chat to communicate, and use a combination of strategy, communication, and mechanical skill to win against other teams. Community-run competitive leagues also tend to feature restrictions such as item bans and class limits. These leagues are often supported by Valve via in-game medals (which are submitted via

2231-444: A player is granted varies per game type. A finite number of lives became a common feature in arcade games and action games during the 1980s, and mechanics such as checkpoints and power-ups made the managing of lives a more strategic experience for players over time. Lives give novice players more chances to learn the mechanics of a video game, while allowing more advanced players to take more risks. Lives may have originated from

2328-435: A primary weapon, secondary weapon, and melee weapon. Engineers have two additional slots for their PDAs , and Spies have an additional slot for their disguise kit. An additional character, Saxton Hale, is playable in the "Versus Saxton Hale" game mode. Although Team Fortress 2 is designed as an open-ended multiplayer experience without an active storyline, the game and additional material feature

2425-447: A release date for the end of the year. In 1999, Valve released Team Fortress Classic , a port of the original Team Fortress, as a free Half-Life mod. Team Fortress Classic was developed using the publicly available Half-Life software development kit as an example to the community and industry of its flexibility. Valve originally planned Team Fortress 2 to have a modern war aesthetic. It would feature innovations including

2522-421: A second time. They attributed the delay to development switching to its new in-house engine, Source . Following the announcement, Valve released no news on the game for six years. Walker and Cook worked on various other Valve projects; Walker was project lead on Half-Life 2: Episode One and Cook worked on Valve's content distribution platform, Steam . Team Fortress 2 became a prominent example of vaporware ,

2619-524: A shared environment. MIDI Maze , an early first-person shooter released in 1987 for the Atari ST , featured network multiplay through a MIDI interface before Ethernet and Internet play became common. It is considered the first multiplayer 3D shooter on a mainstream system, and the first network multiplayer action-game (with support for up to 16 players). There followed ports to a number of platforms (including Game Boy and Super NES ) in 1991 under

2716-427: A significantly different experience of the game. In games with light asymmetry, the players share some of the same basic mechanics (such as movement and death), yet have different roles in the game; this is a common feature of the multiplayer online battle arena (MOBA) genre such as League of Legends and Dota 2 , and in hero shooters such as Overwatch and Apex Legends . A first-person shooter that adopts

2813-414: A single server. Team Fortress 2 is the first of Valve's multiplayer games to provide detailed statistics for individual players, such as the total amount of time spent playing as each class, most points obtained, and most objectives completed in a single life . Persistent statistics tell the player how they are performing in relation to these statistics, such as if a player comes close to their record for

2910-451: A tactile quality and giving Team Fortress 2 its distinct look. The bases are designed to allow players to know immediately where they are. RED bases use warm colors , natural materials, and angular shapes, while BLU bases use cool colors, industrial materials, and orthogonal shapes. During the July 2006 Electronic Arts press conference, Valve revealed that Team Fortress 2 would ship as

3007-572: A ten percent discount for those who pre-purchased it via Steam before the October 10 release, as well as the opportunity to participate in the beta test. Since the release of Team Fortress 2 , Valve has continually released free updates and patches through Steam for Windows, macOS, and Linux users; though most patches are used for enhancing the reliability of the software or to make gameplay changes, several patches have been used to introduce new features and gameplay modes, and are often associated with marketing materials such as comics or videos offered on

3104-400: A utility which measures round-trip network communication delays (by the use of ICMP packets). A player on a DSL connection with a 50- ms ping can react faster than a modem user with a 350-ms average latency. Other problems include packet loss and choke, which can prevent a player from "registering" their actions with a server. In first-person shooters, this problem appears when bullets hit

3201-448: A wider narrative centered around Mann Co. The main PvP gamemodes are set during the "Gravel Wars", a conflict between the rival heirs Redmond and Blutarch Mann for which the nine playable characters were hired as mercenaries . Gray Mann later emerges as the third competitor, killing his two brothers and forcing Saxton Hale to rehire the mercenaries to protect Mann Co. from Gray's robot army in

Players rotate using the input device to perform their turn such that each is taking a turn on the "hot-seat". Not all local multiplayer games are played on the same console or personal computer. Some local multiplayer games are played over

3492-445: Is usually credited with introducing multiple lives to video games. Lives were important in these games because the desire to avoid the finality of the player character's death compelled players to insert more quarters, making the maximum amount of profit. Later, refinements of health, defense and other attributes , as well as power-ups , made managing the player character's life a more strategic experience and made lost health less of

3589-730: The Dartmouth Time-Sharing System (DTSS) had recently gained the ability to support multiple simultaneous users, and that games were the first use of the functionality. DTSS's popular American football game, he said, now supported head-to-head play by two humans. The first large-scale serial sessions using a single computer were STAR (based on Star Trek ), OCEAN (a battle using ships, submarines and helicopters, with players divided between two combating cities) and 1975's CAVE (based on Dungeons & Dragons ), created by Christopher Caldwell (with artwork and suggestions by Roger Long and assembly coding by Robert Kenney) on

3686-598: The Guinness World Record for best selling MMO video game. This category of games requires multiple machines to connect via the Internet; before the Internet became popular, MUDs were played on time-sharing computer systems and games like Doom were played on a LAN. Beginning with the Sega NetLink in 1996, Game.com in 1997 and Dreamcast in 2000, game consoles support network gaming over LANs and

In 2020, the majority of households in the United States have an occupant that plays video games, and 65% of gamers play multiplayer games with others either online or in person. For some games, "multiplayer" implies that players are playing on the same gaming system or network. This applies to all arcade games , but also to

By the early 2010s online gaming had become a mainstay of console platforms such as Xbox and PlayStation . During the 2010s, as the number of Internet users increased, two new video game genres rapidly gained worldwide popularity – multiplayer online battle arena and battle royale game , both designed exclusively for multiplayer gameplay over

4753-611: The Mann vs Machine cooperative horde-shooter mode. The original Team Fortress was developed by the Australian team TF Software, comprising Robin Walker and John Cook, as a free mod for the 1996 PC game Quake . In 1998, Walker and Cook were employed by Valve , which had just released its first game, Half-Life . Valve began developing Team Fortress 2 as an expansion pack for Half-Life using Valve's GoldSrc engine, and gave

Themed patches have also been released, such as a yearly Halloween -themed event called "Scream Fortress", where players may obtain unique items available only during a set period around the holiday. Other new features have given players the ability to craft items within the game from other items, trade items with other players, purchase in-game items through funds in Steam, and save and edit replay videos that can be posted to YouTube. Valve has released tools to allow users to create maps, weapons, and cosmetic items through

In April 2015, Valve announced that a dedicated competitive mode would be added to Team Fortress 2 , utilizing skill-based matchmaking ; closed beta testing began in the following year. The competitive mode was added in the "Meet Your Match" update, released on July 7, 2016. Ranked matches are played six-vs-six, with players ranked in thirteen ranks based on win/losses and an assessment of their skills. Ranked matchmaking will balance players based on their ranks and rating. A similar matchmaking approach has been added for casual games for matches of 12-vs-12 players, but uses

Other popular formats include "Highlander", a 9v9 format with a limit of one player per each of the nine classes, as well as a Sixes-inspired 7v7 variant thereof known as "Prolander" to allow for strategically switching classes during a competitive game. Team Fortress 2 features nine playable classes, which are evenly split and categorized into "Offense", "Defense", and "Support". Each class has strengths and weaknesses and must work with other classes to be efficient, encouraging strategy and teamwork. Each class has at least three default weapons:

5141-425: The asymmetrical multiplayer system is Tom Clancy's Rainbow Six Siege . Giving players their own special operator changes every player's experience. This puts an emphasis on players improvising their own game plan given the abilities their character has. In games with stronger elements of asymmetry, one player/team may have one gameplay experience (or be in softly asymmetric roles) while the other player or team play in

5238-420: The basic elements of each class remained, those being one primary weapon, one secondary weapon, and one melee weapon. The game was released with six official maps, although over one hundred maps have since been included in subsequent updates, including community-created maps. When a player chooses a game-mode for the first time, an introductory video is played, showing how to complete its objectives. During matches,

Multiplayer video game The history of multiplayer video games extends over several decades, tracing back to the emergence of electronic gaming in the mid-20th century. One of the earliest instances of multiplayer interaction was witnessed with the development of Spacewar! in 1962 for the DEC PDP-1 computer by Steve Russell and colleagues at

5529-404: The casual player until it was shut down in 2013. Some networked multiplayer games, including MUDs and massively multiplayer online games (MMOs) such as RuneScape , omit a single-player mode. The largest MMO in 2008 was World of Warcraft , with over 10 million registered players worldwide. World of Warcraft would hit its peak at 12 million players two years later in 2010, and in 2023 earned

A server that is geographically closer to the player's connection will often provide a lower ping. Data packets travel faster to a location that is closer to them. How far the device is from an internet connection ( router ) can also affect latency. Asymmetrical multiplayer is a type of gameplay in which players can have significantly different roles or abilities from each other – enough to provide

Ken Wasserman and Tim Stryker identified three factors which make networked computer games appealing: John G. Kemeny wrote in 1972 that software running on

6305-830: The form of submissions made through the Steam Workshop . In June 2011, the game became free-to-play , with revenue derived from microtransactions for in-game cosmetics . A 'drop system' was also added and refined, allowing free-to-play users to periodically receive in-game equipment and items. Though the game has had an unofficial competitive scene since its release, both support for official competitive play through ranked matchmaking and an overhauled casual experience were added in July 2016. From early 2020 to mid-2024, cheating bots overrunning Valve’s official matchmaking servers led to fans holding several online protests, and eventually Valve adding new policies regarding game bans. In most game modes, two teams, RED and BLU, compete for

6402-416: The game becoming free-to-play from the use of both voice and text chat in game. On June 24, all players were restricted from changing their Steam username while connected to any Valve matchmaking server or any server with display name updates disabled. The change was implemented to prevent bots from changing their display name to impersonate legitimate players, which allowed the bots to avoid being kicked due to

On October 25, 2024, an update was released that fixed a bug where the BLU Team Scout was wearing brown pants rather than blue pants matching

6790-450: The game. Team Fortress 2 contains five core game modes. There are several alternative game modes in Team Fortress 2 . These modes consist of a small number of maps and detach from the core game modes in some way. These modes are not categorized with the other modes, and instead have their own separate sections in the game. Team Fortress 2 is played competitively through multiple leagues. The North American league, ESEA , supports

6887-458: The handicap it was in early arcade games. Lives and game over screens became thought of as outmoded concepts and holdovers from arcade games that were unnecessary when players had already paid for the game. They also discouraged the player from playing the game fairly, with players in games such as Doom resorting to save scumming in order to preserve their lives rather than start from an in-game checkpoint with their lives depleted, and getting

6984-410: The impact of the leak could be determined. Valve confirmed the legitimacy of the code leaks, but stated they do not believe it affects servers and clients running the latest official builds of either game. On May 1, 2020, shortly following the death of the voice actor of the Soldier, Rick May , Valve released an update to Team Fortress 2 , adding a tribute to his voicework as the Soldier in the form of

Walker stated that Valve had learned that the more players Team Fortress 2 had, the more value it had for each player. The move came a week after Valve introduced several third-party free-to-play games to Steam and stated they were working on a new free-to-play game. Within nine months of becoming free to play, Valve reported that revenue from Team Fortress 2 had increased by

7178-560: The late 1980s, enabling players to connect multiple computers for multiplayer gameplay, popularized by titles like Doom and Warcraft: Orcs & Humans . Players can also play together in the same room using splitscreen . Some of the earliest video games were two-player games, including early sports games (such as 1958's Tennis For Two and 1972's Pong ), early shooter games such as Spacewar! (1962) and early racing video games such as Astro Race (1973). The first examples of multiplayer real-time games were developed on

7275-472: The maximum size and composition of a team and can drastically change the impact of a single player's gameplay or choice of class. The two most basic formats consist of 12v12 and 6v6 ("Sixes"), the two being used on official Valve servers for casual and competitive modes respectively with no additional limitations. Most competitive leagues host Sixes but include limits on certain classes and weapons to preserve traditional, skill-based playstyles, for example limiting

7372-495: The multiplayer component of The Orange Box . A conference trailer showcasing all nine of the classes demonstrated for the first time the game's cartoon-like visual style. Valve's president, Gabe Newell , said that the team's goal was to create "the best-looking and best-playing class-based multiplayer game". A beta release of the entire game was made on Steam on September 17, 2007, for customers who had pre-purchased The Orange Box , who had activated their Black Box coupon, which

7469-522: The need to wait for an invitation. On February 14, 2013, Valve announced the full release of Team Fortress 2 for Linux. From then to March 1, anyone who played the game on Linux would receive a free Tux penguin, which can be equipped in-game. Team Fortress 2 was announced in March 2013 to be the first game to officially support the Oculus Rift , a consumer-grade virtual reality headset. A patch

7566-559: The other games within The Orange Box . The updates released on PC and planned for later release on Xbox 360 include new official maps and game modes, as well as tweaks to classes and new weapons that can be unlocked through the game's achievement system.

7663-480: The player from death contingent on successfully executing a QTE , as in Batman: Arkham Asylum . It is common in action games for the player to have multiple lives and chances to earn more in-game. This way, a player can recover from making a disastrous mistake. Role-playing games and adventure games usually grant only one, but allow player-characters to reload a saved game . Lives set up

7760-554: The player. Many older video games feature cheat codes that allow you to gain extra lives without earning them throughout gameplay. One example is Contra , which added the option to input the Konami code to get 30 extra lives. In modern times, some free-to-play games, such as the Candy Crush Saga trilogy, capitalize on the multiple life system to create an opportunity to earn more microtransactions . In such games,

7857-420: The price. Because of the cost of patching during the seventh generation of video game consoles , Valve has been unable to provide additional patches to the Xbox 360 version since 2009, effectively cancelling development of the console versions. On March 29, 2023, the servers for the PlayStation 3 version of Team Fortress 2 went offline. On June 10, 2010, Team Fortress 2 was released for macOS , shortly after

7954-454: The release of Steam for macOS. The release was teased by way of an image similar to early iPod advertising , showing a dark silhouette of the Heavy on a bright green background, his "Sandvich" highlighted in his hand. Virtual earbuds , which can be worn when playing on either macOS or Windows once acquired, were given to players playing the game on macOS before June 14, though the giveaway period

8051-416: The situation where dying is not necessarily the end of the game, allowing the player to take risks they might not take otherwise, or experiment with different strategies to find one that works . Multiple lives also allow novice players a chance to learn a game's mechanics before the game is over. Another reason to implement lives is that the ability to earn extra lives provide an additional reward incentive for

8148-454: The team's color scheme. The update received notable attention due to the absurdity of fixing such a bug 17 years into the game's lifespan. It was reverted a day later, citing that it led to inconsistencies with the cosmetics that were based on the broken color scheme. On June 23, 2011, Valve announced that Team Fortress 2 would become free-to-play . Unique equipment including weapons and outfits would be available as microtransactions through

8245-536: The term "1-up" to designate an extra life first appeared in Super Mario Bros. , where a 1-Up could be obtained in several ways, including grabbing a green "1-Up Mushroom", collecting 100 coins, using a Koopa shell to kill 8 or more consecutive enemies, and jumping on 8 or more consecutive enemies without touching the ground. The term quickly caught on, seeing use in both home and arcade video games. A number of games included an exploitable design flaw called

8342-464: The title Faceball 2000 , making it one of the first handheld, multi-platform first-person shooters and an early console example of the genre.

On June 16, 2020, Valve responded to this by restricting accounts that have not paid for Mann Co. Store items or purchased Team Fortress 2 prior to

8536-692: The widespread availability of the Internet which allowed players to play against each other simultaneously, but remains an option in many strategy-related games, such as the Civilization series . Coordination of turns are subsequently managed by one computer or a centralized server. Further, many mobile games are based on sporadic play and use social interactions with other players , lacking direct player versus player game modes but allowing players to influence other players' games, coordinated through central game servers, another facet of asynchronous play. Online cheating (in gaming) usually refers to modifying

8633-631: Was based on 1974's single-user, turn-oriented BASIC program STAR, written by Michael O'Shaughnessy at UNH. Wasserman and Stryker in 1980 described in BYTE how to network two Commodore PET computers with a cable. Their article includes a type-in , two-player Hangman , and describes the authors' more-sophisticated Flash Attack . SuperSet Software 's Snipes (1981) uses networking technology that would become Novell NetWare . Digital Equipment Corporation distributed another multi-user version of Star Trek , Decwar , without real-time screen updating; it

8730-505: Was first shown at E3 1999 as Team Fortress 2: Brotherhood of Arms , where Valve showcased new technologies including parametric animation , which blended animations for smoother, more lifelike movement, and Intel 's multi-resolution mesh technology, which dynamically reduced the detail of distant on-screen elements to improve performance.

Later, on December 20, 2012, Valve opened up access to the beta, including Team Fortress 2 , to all Steam users without

9021-414: Was made to the client to include a "VR Mode" that can be used with the headset on any public server. In April 2020, source code for 2018 versions Team Fortress 2 and Counter-Strike: Global Offensive was leaked online. This created fears that malicious users would use the code to make remote code execution software and attack servers or players' computers. Several fan projects halted development until

9118-827: Was partially attributed to the display of a player's name above their cybertank. There followed 1993's Doom , whose first network version allowed four simultaneous players. Play-by-email multiplayer games use email to communicate between computers. Other turn-based variations not requiring players to be online simultaneously are Play-by-post gaming and Play-by-Internet . Some online games are " massively multiplayer ", with many players participating simultaneously. Two massively multiplayer genres are MMORPG (such as World of Warcraft or EverQuest ) and MMORTS .

Its development was led by John Cook and Robin Walker ,

9312-424: Was the first game to implement the Source engine's new facial animation features. Valve abandoned the realistic style when it became impossible to reconcile it with the unrealistic gameplay, with opposing armies having constructed elaborate bases directly adjacent to each other. Valve designed each character, team, and equipped weapon to be visually distinct, even at range; for example, the coloring draws attention to

9409-554: Was widely distributed to universities with DECsystem-10s. In 1981 Cliff Zimmerman wrote an homage to Star Trek in MACRO-10 for DECsystem-10s and -20s using VT100-series graphics. "VTtrek" pitted four Federation players against four Klingons in a three-dimensional universe. Flight Simulator II , released in 1986 for the Atari ST and Commodore Amiga, allowed two players to connect via modem or serial cable and fly together in
