Valve is an American video game developer and publisher founded in 1996 by Gabe Newell and Mike Harrington. The company is based in Bellevue, Washington.[1] Valve's first game was Half-Life, a first-person shooter released in 1998.[2] It received universal acclaim and sold over nine million retail copies.[3][4] Alongside Half-Life's launch, Valve released development tools to enable the player community to create content and mods.[5] The company then proceeded to hire the creators of popular mods, such as Counter-Strike, which became the most popular multiplayer first-person shooter for the next decade.[1]
Valve continued their trend of developing predominantly first-person video games in the 2000s with a number of critically successful releases. In 2004, they released the highly anticipated sequel Half-Life 2 through their own digital distribution service Steam. The game sold over 10 million copies and was met with acclaim. Valve released two subsequent episodes for Half-Life 2 and later packaged those games together with the puzzle game Portal and the multiplayer shooter Team Fortress 2 in a collection known as The Orange Box.[6] By the end of 2008, combined retail sales of the Half-Life series, Counter-Strike series and The Orange Box had surpassed 32 million units.[4] Newell also projected that digital sales of Valve's games would eventually exceed retail sales as Steam continued to grow.[4][7] In the late 2000s, Valve released two zombie-themed first-person shooters focusing on cooperative gameplay with the Left 4 Dead series. The company continued to release multiplayer games with the launches of Counter-Strike: Global Offensive and Dota 2,[6] both of which have large esports communities fostered by Valve.[8] During the 2010s, Valve began focusing on supporting their established multiplayer games with regular content updates.[6][9][10][11] In the late 2010s, Valve began investing in virtual reality and started to develop games and other software that make use of the technology, such as Half-Life: Alyx.[12][13]
Valve is considered to be one of the most important and influential companies in the gaming industry.[14] The reception of their games, along with the creation of Steam, has prompted some publications to list Valve as one of the top game developers of all time,[15][16] and the most powerful company in PC gaming.[17] In 2013, Newell received a BAFTA Fellowship award with the BAFTA Games Committee recognizing the impact Valve had left on the gaming industry in producing critically and commercially successfully game franchises.[5]

Canceled and unreleased games
Several games announced by Valve as being in development have since been put on hold indefinitely or cancelled.
Half-Life
- Half-Life: Hostile Takeover: An expansion pack for the original Half-Life developed by 2015, Inc.,[139] reportedly cancelled in 2000.[140]
- Half-Life 2: Episode Three: Announced in 2006 with a release date of late 2007, and cancelled due to scope creep, unsatisfactory internal experiments, and the desire to develop the Source 2 engine first.[141]
- Untitled Half-Life 2 episode: Developed by Junction Point Studios and led by Warren Spector. Development ceased when Junction Point signed a deal with Disney Interactive Studios to develop Epic Mickey.[142] Valve took Junction Point's project and passed to Arkane Studios.[143]
- Ravenholm (also known as Return to Ravenholm or Half-Life 2: Episode Four): Developed by Arkane Studios around 2006–2007, with Opposing Force protagonist Adrian Shephard as the player character and Father Grigori from Half-Life 2 in a supporting role.[143]
- Half-Life 3: A version of Half-Life 3 was in development on the Source 2 engine from 2013 to 2014. Valve planned to incorporate procedurally generated levels alongside a "crafted experience" so that no two playthroughs of the game would be identical. It was cancelled as Source 2 was not yet stable enough to support full-scale development.[144]
- Borealis: A virtual reality game led by writer Marc Laidlaw in development in 2015, set aboard the time-travelling ship Borealis. It was cancelled as it failed to gain momentum.[144]
Others
- Untitled submarine game: One of Valve's earliest game ideas was for a submarine game, with Valve co-founder Mike Harrington seeing an opportunity to create "fantastic underwater visuals and gameplay". It is unknown whether it ever advanced beyond the conceptual stage.[145]
- Prospero: A third-person exploration game with a science fantasy theme. The project was in development at the same time as Half-Life.[146] Prospero's development team transitioned to work on Half-Life, which had gained more traction.[147]
- Untitled role-playing game (I): A fantasy, action role-playing game about fairies that was in a prototype phase and cancelled prior to Left 4 Dead's release.[148]
- The Crossing: A first-person shooter developed in collaboration with Arkane Studios. The project was announced in 2007 and put on hold in May 2009.[149]
- Stars of Blood: A space pirate game. In November 2012, Newell revealed the project's name and confirmed that it was no longer in development.[150]
- Left 4 Dead 3: An open-world sequel to Left 4 Dead 2 that was set in Morocco. It was cancelled when it became clear that the Source 2 engine was not yet ready to support full-scale game development.[144]
- Hot Dog: Another attempt at creating a Left 4 Dead game, codenamed so that fans would not recognize it if its name were leaked.[144]
- Untitled role-playing game (II) – A fantasy RPG that was inspired by The Elder Scrolls, Dark Souls, and Monster Hunter series. It was at one point resurrected as a single-player RPG about the Dota 2 character Axe before it was shelved again.[144]
- A.R.T.I.: A lighthearted voxel-based game that allowed for open-ended creation and destruction in a vein similar to Minecraft. It was resurrected as a VR game but shelved again when Half-Life: Alyx eclipsed its development.[144]
- SimTrek: A virtual reality game developed primarily by the creators of Kerbal Space Program. It was cancelled during the development of Half-Life: Alyx.[144]
- In the Valley of Gods: A period adventure game set in 1920s Egypt developed by Campo Santo, a studio acquired by Valve in 2018. It was put on hold in late 2019, with the designers shifting to other Valve projects.[151]
