->''[[{{Memes/ValveSoftware}} Meanwhile, at Valve...]]''

Valve Software was founded in 1996 by former Microsoft employees Gabe Newell and Mike Harrington, inspired by learning that the only piece of software more commonly installed on DOS computers than Windows was ''VideoGame/{{Doom}}''. Once they secured a license to use the ''VideoGame/{{Quake}}'' engine, Valve set about to create their first game... ''VideoGame/HalfLife1'' was released in 1998 and ever since, Valve has been known for their revolutionary and amazing First-Person action games. In 2004, they launched one of the first digital distribution platforms, along with the sequel to ''Half-Life'' which used it exclusively -- and thus was born UsefulNotes/{{Steam}}, which went on to become the biggest digital distribution platform for Windows and a license to print money for Valve. And, because Valve is such a small company, they have developed something of a reputation for having literally more money than they know what to do with. A fair bit of it seems to go into flying fans out to visit their headquarters. [[http://www.escapistmagazine.com/news/view/94640-L4D-Modder-Raising-Funds-to-Fly-Gabe-Newell-to-Australia Just don't get presumptuous.]]

Valve is somewhat unique in that it has retained the flat organizational model of the early computing industry. All development is handled by ad hoc, self-directed development teams who work by consensus and debate, without any sort of formal management structure issuing orders and dictates. This quasi-anarchic business model is the source of both their endless creativity and inspiration and their endless delays and organizational confusion, with the now-mythical Half-Life (Episode) 3 being the most prominent victim.

Valve's in-house game engine (Source, the successor to their ''VideoGame/{{Quake}}''-based [=GoldSrc=] engine) is publicly available for other commercial developers to license, but for those interested in creating free [[GameMod mods]], the level editor and several other modding tools are available for free with the purchase of any game. (And most of the other handy tools have been developed by third parties as freeware.) To this end, the engine has become the basis for a legendary number of mods, including several that function as standalone games in their own right.

In fact, the majority of Valve's own oeuvre -- ''Counter-Strike'', ''Day of Defeat'', ''Team Fortress'', ''Dota 2'', and the free ''Alien Swarm'' -- were originally the product of mod teams (though only the first two were mods of their own engine originally), who were then recruited to work for Valve and whose games were re-released as commercial titles. Of its flagship titles, only the ''Half-Life'' series was actually created by Valve directly; ''Portal'' was adapted from a concept game made by a bunch of college students, and ''Left 4 Dead'' was started by another company that Valve later bought out.

In March 2010, they announced that they would be porting Steam, the Source Engine, and their entire back catalog to UsefulNotes/MacOS X. In June 2010, at E3, Gabe Newell made a surprise announcement that Portal 2 and Steam would be coming to the Playstation 3 to thunderous applause. They later gained the love of 99% of Linux users when they released the public beta of a Linux port in late December 2012, with an official release appearing in February 2013. At present, this is only officially supported on Debian-based distros, but other users have had some success at running it on Fedora- and Arch-based systems.

They are [[Memes/ValveSoftware a frequent source]] [[FountainOfMemes of memes]]. They also have fairly active blogs for their big games.

They have a level one [[VideoGame/TeamFortress2 Sentry]] [[http://www.youtube.com/watch?v=j1kccz1qziE Gun]] [[{{Defictionalization}} in their lobby]] as well as an [[VideoGame/{{Portal}} Aperture Science]] [[http://www.youtube.com/watch?v=LvZhRUsKNG4 Turret]]. They also have a [[http://www.youtube.com/watch?v=YR0WN55p_zI snack bar]] that is pretty dang good.

!!Tropes exhibited by Valve include:
* ArcNumber: For some bizarre reason, Valve is continually stuck on 2. None of their series ever seem to reach a game with "3" in the name, even though a couple have already included more than two games. (Thus spawning the [[MemeticMutation meme]] "Valve can't count to three!") ''Half-Life 2'', ''Left 4 Dead 2'', ''Team Fortress 2'', ''Half-Life 2: Episode 2'', ''Portal 2'', ''[[WebAnimation/ZeroPunctuation Manchester United 0]]''. Now they're even making a second game for [[VideoGame/DefenseOfTheAncients a series they didn't start]].
** Gets even more funny when [[http://www.valvetime.net/threads/new-images-of-half-life-2-episode-4-return-to-ravenholm.243033/ they decided to skip three and go straight to four]].
** Not to mention they're on their second engine, the increasingly dated Source engine. Leaked data points to its successor bearing the [[SarcasmMode incredibly creative name]] "Source 2".
* AscendedFanFic: Every game, save for the ''VideoGame/HalfLife'' series, once started off as a mod, or was inspired by another game.
** ''VideoGame/TeamFortressClassic'' and its sequel, ''VideoGame/TeamFortress2''.
** The ''VideoGame/CounterStrike'' series.
** The ''VideoGame/DayOfDefeat'' series.
** Much of ''Portal'' was inspired by the game ''Narbacular Drop'', created by [=DigiPen=] students, many of whom where hired by Valve.
*** A mechanic from the sequel, ''VideoGame/{{Portal 2}}'', originated from the similarly student-created ''Tag: The Power of Paint". Valve also hired many of this game's developers.
** ''VideoGame/Left4Dead'' was inspired by a ''VideoGame/CounterStrike'' zombie mod.
** ''VideoGame/AlienSwarm'' was an ''VideoGame/UnrealTournament2004'' mod.
** ''VideoGame/{{Dota 2}}'' was originally a mod for Warcraft 3 (which was itself based on a Starcraft mod).
* BadassBookworm: [[VideoGame/HalfLife Gordon Freeman]], [[VideoGame/TeamFortress2 The Engineer, and The Medic]].
* BigFun: Gabe Newell, the face of Valve. As well as [[VideoGame/TeamFortress2 Heavy Weapons Guy]]!
* BodyHorror: The logos used, what with valves coming out of the human body.
* BootstrappedTheme: [[https://www.youtube.com/watch?v=o5iUt1EtUqs Hazardous Materials]] from the ''VideoGame/HalfLife1'' soundtrack is the music from the logo for Creator/ValveSoftware.
* EverythingsBetterWithPlushies: [[VideoGame/Left4Dead The Tank, Hunter, and Boomer!]]

* EyeScream: The original logo, pictured above. [[labelnote:What it is]]A picture of a man with a valve in his left eye.[[/labelnote]]
* FeatheredFiend: In ''VideoGame/{{Portal 2}}'', they attack robots. In ''VideoGame/Left4Dead'', they dickishly awaken hordes of zombies with very sensitive hearing. ''In VideoGame/TeamFortress2'', they enjoy ''flying into open wounds''.
-->'''[[VideoGame/TeamFortress2 Medic]]''': "Archimedes! No! [shoos the dove away from Heavy's open chest cavity] It's filthy in zhere! Eugh! [turns to Heavy] ''Birds.'' [chuckles]"
** Apparently an axed line from ''VideoGame/{{Portal 2}}'' involved Cave Johnson warning test subjects about [[EyeScream birds that may be pecking around inside your eye sockets]].
* TheFourthWallWillNotProtectYou: The new and updated 2012 "open your mind" intro has Mr. Valve ''slowly turning his head towards you''.
* GameMod: Part of the reason why their games are so popular is because their games are ''very'' mod-friendly. So much that full games themselves were created from mods (and Valve seems to specialize in making mods into full games).
** As time goes on, Valve seems to be making their games even more mod-friendly. With the introduction of the Steam Workshop, Valve has given modders a central location to post their mods. This has made installation of mods as simple as the click of a button, making them accessible to the masses.
* GasCylinderRocket: The Source engine includes a physics object for this.
* GratuitousGerman: The Axis soldiers from ''Day of Defeat'' and TheMedic from ''VideoGame/TeamFortress2''.
* HeroicMime: [[VideoGame/HalfLife Gordon Freeman]], [[VideoGame/{{Portal}} Chell]], [[VideoGame/{{Portal 2}} Atlas and P-Body]] as well as Adrian Shepherd and Barney Calhoun in the ''Half-Life'' expansions (though Barney talks when he's an [[NonPlayerCharacter NPC]] in other games).
* {{Homage}}: Many of their promotions for the port of Steam to Mac were homages of famous ads in Apple's past, like the "1984" commercial (replacing the woman with the baton with Alyx Vance and a crowbar, naturally), [[VideoGame/TeamFortress2 Heavy Weapons Guy]] as one of the earbud-wearing silhouettes (If you bought or played ''VideoGame/TeamFortress2'' on a Mac in the days following the port, you received a pair), Francis proclaiming "I hate different.", and the "Hi, I'm a Mac, and I'm a PC" ad with a ''VideoGame/{{Portal}}'' turret representing Macs and the ''VideoGame/TeamFortress2'' RED Level 1 Sentry representing PC's.
* HurricaneOfPuns: Valve loves these - just look at any game they've made!
** A fan once emailed Gabe asking what tea Gordon Freeman drinks with his "hipster glasses on", and he responded [[http://media.photobucket.com/image/recent/spike1233/MITea.jpg "[=MITea=]"]].
* KnifeNut: Gabe has an impressive (100+) knife collection [[http://www.youtube.com/watch?v=Nq2X7KRt1hg#t=2m28s in his office]].
* InformedFlaw: Pops up a lot in Valve's games. For example:
** ''VideoGame/Left4Dead'' and ''VideoGame/Left4Dead2'': Bill and Coach are both the oldest members of their respective teams, and both have suffered a knee injury (Bill's is from serving in Vietnam, while Coach's is from football). These injuries only seem to affect them in cutscenes.
** ''VideoGame/{{Portal 2}}'': [=GlaDOs=] frequently makes fun of Wheatley for being an idiot. There are however hints throughout the second game, especially in the second half, that Wheatley isn't as dumb as he comes across. Then again, sometimes he is. He zig-zags.
** ''VideoGame/TeamFortress2'': The mercenaries' bosses, Helen and Miss Pauling, seem to hint that the mercs are brain-damaged, and can barely read. But Engineer and Medic are both brilliant inventors, Heavy has a [=PhD=] in Russian Literature (that he earned in Soviet Russia, when anti-intellectualism was prominent), Soldier is a lawyer, an exorcist, ''and'' a priest, Scout may be more well-read than he comes across, Sniper rigging a WOODEN tribal shield to electrocute on contact, as well as being possibly the [[OnlySaneMan most sane of all]], tied with the Spy, that has the connections and resources to actually research a [[YourMom "Your Mom" joke]], Pyro somehow [[spoiler:became head of an engineering company]]...
* MegaCorp: A powerful but [[CorruptCorporateExecutive unethical]] corporation dealing in research and development and military technology and showing cavalier [[NoOSHACompliance neglect for safety]] shows up in many of their franchises. [[VideoGame/HalfLife Black Mesa]] is PlayedStraight, but [[VideoGame/{{Portal}} Aperture Science]] and [[VideoGame/TeamFortress2 Mann. Co]] are PlayedForLaughs.
* OminousLatinChanting: Not exactly Latin (more "Ohhh" and/or unintelligible chanting), but composer Mike Morasky seems to like this a lot. See "TANK!" for the creepy boss variety, and "A Little Heart To Heart" and "MEDIC!" (because it ties in with Medic's God complex).
* PoorCommunicationKills: Valve has become infamous for their lack of community interaction, which reached its height during the [[http://www.forbes.com/sites/insertcoin/2013/11/02/valve-forgot-diretide-halloween-and-dota-2-fans-are-not-pleased/ Diretide controversy]] in 2013, where they canceled a highly-anticipated event for ''Videogame/DOTA2'' without actually telling anyone, resulting in a massive outcry, though they have since stated that they will interact more with the community. This is of course saying nothing about Episode 3, which had languished in DevelopmentHell for years before seemingly being cancelled: all without nary a word from Valve.
* {{Retcon}}: The origin story for ''Left 4 Dead'' has been revised over time; depending on who you asked and when, it was either a ''Counter-Strike'' mod, a commercial product by a small team that Valve bought out, or implied to have been developed fully in-house from the beginning (see What Could Have Been, below).
* RunningGag: Gabe Newell's weight[[note]][[http://wiki.teamfortress.com/w/images/e/ef/Engineer_negativevocalization05.wav reaction here]][[/note]], Robin Walker's obsession with hats, their delays, their apparent inability to count to three...
* PlagueOfGoodFortune: Steam ballooning into the main PC gaming market did not help Valve's {{Schedule Slip}}s, as large amounts of manpower have to be directed to managing it.
* SelfDeprecation: They favor this brand of humor where VideoGame/TeamFortress2 is concerned. The [=TF2=] development staff are {{flanderized}} as all being obsessed with hats to the point of defying all common sense. And when Meet the Spy got leaked, Valve decided to give themselves a Corporate Achievement making fun of themselves for it [[note]]Welcome to the Internets: Fail to understand what Private means on YouTube.[[/note]]
* SuspiciouslySpecificDenial: In the [[http://assets.sbnation.com/assets/1074301/Valve_Handbook_LowRes.pdf online version of its employee handbook]], the company boasts about its flat organizational style:"''... we don't have any management, and nobody 'reports to' anybody else. We do have a founder/president, but even he isn't your manager.''" If you think that suggests this trope, you're not alone. Someone at Valve thought the same thing, apparently, and went so far as to not only use it more explicitly but lampshade it in the glossary at the end of the handbook:
-->'''Gabe Newell'''''Of all the people at this company who aren't your boss, Gabe is the MOST not your boss, if you get what we're saying.''
* TakeThat: Valve has been known for not exactly holding their tongue, which has gotten them some [[InternetBackdraft flak]] over the things they have said about certain topics.
** The most well known was Gabe Newell's initial reaction to the UsefulNotes/PlayStation3, which he said that the system was a "[[http://www.1up.com/news/gabe-newell-ps3-total-disaster total disaster on so many levels]]". This caused many of the early adopters that dared to adopt the then expensive platform to respond. Even though Gabe didn't see the [=XBox=] as very good of a platform, either, Valve decided to develop in house for it. Gabe didn't help smooth over relations with the [=PS3=] fanbase by outsourcing The Orange Box's [=PS3=] port to Creator/ElectronicArts, in which was seen as a total disaster. Over the years that followed, Gabe tried to slowly mend the relationship while still holding to his convictions, with having a new criticism for the system when a previous one was either fixed or debunked. Gabe had even admitted that he had many requests for Valve to develop for the system.
*** Finally, in 2010, Gabe Newell [[CrossingTheBurntBridge made things right with PS3 owners]] when he came on a Sony stage at E3 to announce that ''Portal 2'' would be released on the Playstation 3, touting the system's open-ended nature that would allow them to provide automatic updates (a feature many of their other games on the PC enjoy), cross-platform multiplayer with the PC version, and Steamworks available through the game to seamlessly link the Steam achievements for the game with the Playstation 3 trophies for the same game. He even invoked some Self-deprecation, saying that he had been a little vocal about the current generation of game platforms, and that the Sony advertising mascot at the time, Kevin Butler, was introduced to him as the "VP of sharpening things"
** Despite his outspoken nature, he has at times been somewhat nervous on stage, being more comfortable with one-on-one interviews. He was also nervous (as he was during the Sony megaton) during a presentation in which he touted EA's involvement in Team Fortress 2, perhaps because he wasn't happy with how EA handled the [=PS3=] Orange Box port (he had said during the interim between his infamous quote to the Portal 2 reveal that he regretted his words and wanted to make things right with [=PS3=] owners).
* TheUnintelligible: Atlas and P-Body chirp to each other to communicate, and all the zombies in the ''Left 4 Dead'' series make weird noises (crying, howling, grumbling, belching, or mad laughing). And of course, the Pyro.
* TwoferTokenMinority: Chell from ''Portal'', Rochelle from ''Left 4 Dead 2'', Demoman from ''Team Fortress 2'', and Alyx Vance from ''Half-Life 2''
* UnbrokenFirstPersonPerspective: The original ''Half-Life'' was the TropeCodifier for the use of this trope in a narrative context. It's become something of a hallmark of the studio's games ever since, and was used in ''Half-Life 2'' (and its episodes) and both ''Portal'' games.
