Valve

August 24 1996

Valve is founded as an L.L.C. in Kirkland, WA by former Microsoft employees Gabe Newell and Mike Harrington, instrumental minds behind nearly three generations of the Windows operating system. Their first order of business is to acquire the licensing rights to the original Quake engine from id Software, which they immediately fell in love with. This soon becomes the heavily modified Goldsrc engine with roughly 70% of the original code being rewritten.

November 1 1996

Two teams work on two separate titles to launch the Valve brand; Quiver, an action-packed first-person shooter, and Prospero, a Myst-style adventure drama. Both get relatively far into development and are set for late ’97 release dates.

January 1 1997

Gabe Newell begins a long-standing Valve tradition and decides to regroup his creative teams to start from scratch on a single title, combining the drama of Prospero with the action of Quiver in what would be a groundbreaking achievement for the video game industry – an FPS with a decent, coherent storyline. The new project is dubbed Half-Life, which is first shown to the public at the E3 convention to generally appreciative murmurs.

May 1 1998

Valve acquires TF Software PTY Ltd., the makers of the original Team Fortress mod for Quake, with the intention of developing and releasing a new stand-alone title, Team Fortress 2. This would ultimately take the company nine years to do.

November 19 1998

Half-Life is released through Sierra On-Line after some initial difficulty in finding a publisher largely due to Valve’s reputation of being overly ambitious. It quickly becomes a bestseller and wins high critical acclaim, snagging no less than 51 Game of the Year awards from various publications. To this day it is generally regarded as one of the greatest games ever made. In an extra folder on the installation CD could be found Worldcraft, an intuitive level editor that would spawn an unparalleled mod-making revolution.

January 1 1999

With the great success and flood of cash revenue coming in off of Half-Life, programmers set to work on an even heavier modification of the Goldsrc engine. This is technically why all future expansions and titles up until the release of Half-Life 2 are developed by third-parties. The new engine takes several years to finish and would make use of lighting, physics, particle effects and model animation in unprecedented and revolutionary new ways. It is dubbed simply “Source” and thanks to its modular nature it is still receiving amazing new features and upgrades with every new title that uses it. Meanwhile the writing and art teams work very, very secretly on concepts for a sequel to Half-Life.

January 1 1999

The first Team Fortress 2 media is released, showing a sharp contrast from the cartoonish original with the much more realistic look of modern combat military games, as well as a “commander” on each team who could oversee and direct their troops.

After a while this media is spirited away and Team Fortress 2 becomes vaporware.

February 12 1999

Half-Life: Uplink, the official Half-Life demo, is released. The demo features parts of the original Half-Life that didn’t make the final cut. (See the original press statement here).

March 25 1999

A small Half-Life mod in development called Counter-Strike moves its official website hosting to Planet Half-Life (then Contaminated.net), a relationship that would last until the release of Steam and the official website being replaced with a Steam Store page.

April 7 1999

Team Fortress Classic is released. It is essentially a remake of the original Quake mod on Half-Life’s Goldsrc engine, done as a “proof-of-concept” before continuing on with Team Fortress 2’s development. It is packaged with Half-Life version 1.0.0.9 and would be included on all future retail copies of Half-Life thereafter.

April 22 1999

Sierra On-Line announces that Half-Life will be made available for the Mac platform later in the year. The port was being developed by Logicware, a company known for successful Macintosh game ports and development. After exhaustive work and nearly going gold, the port is ultimately abandoned.

June 18 1999

Minh “Gooseman” Le and Jess “Cliffe” Cliffe release the first public beta of their team-based multiplayer mod Counter-Strike. It is an instant hit with hundreds, if not thousands of players in just weeks.

October 31 1999

Half-Life: Opposing Force is released. This expansion pack, developed by third-party Gearbox Software, takes players out of Gordon Freeman’s H.E.V. suit and puts them into the combat boots of Corporal Adrian Shephard, one of the Marines sent in to clean out Black Mesa. New characters, aliens and weapons set in a lengthy campaign make it a worthy successor to Half-Life.

April 12 2000

Valve announces it has “teamed up with” (read: hired) the Counter-Strike development team.

November 8 2000

Counter-Strike 1.0 is released through Valve, launching one of the largest multiplayer trends of all time. To this day CS 1.6 (the last version update prior to its move to the Source engine) is the most played online PC game excluding MMORPGs.

November 20 2000

Gunman Chronicles, originally just an ambitious Half-Life mod, is released as a stand-alone retail game. GC is the first and only one of two games to use the Goldsrc engine that isn’t an official Half-Life title (the other being James Bond 007: Nightfire).

January 12 2001

In another mod milestone, the first public beta of Day of Defeat is released. Unlike Counter-Strike, it would take a few years before Valve began official sponsorship.

June 12 2001

Half-Life: Blue Shift, originally intended to be a Sega Dreamcast exclusive, is released as a PC exclusive. This second, stand-alone expansion pack puts the player in the shoes of Barney Calhoun, the first security guard you see knocking on the door near the tram tracks in the very first scene of the original game. We know he’s not the one who owes Gordon a beer, but continuity wasn’t all that Blue Shift was lacking. To make up for its 3-hour length and other shortcomings, it’s apologetically packaged with Opposing Force and a shiny new “high-definition” model pack upgrade. It receives lukewarm reviews at best.

March 22 2002

At the Game Developers’ Conference, Valve unveils Steam, which at the time is simply intended to be a digital distribution service. There is no mention made of any of the other features it would ultimately ship with.

January 1 2003

Valve, L.L.C. becomes the Valve Corporation and moves headquarters from Kirkland to Bellevue, WA.

May 1 2003

Valve releases Day of Defeat as an official mod. While it never gains the popularity of Team Fortress Classic or Counter Strike, it nevertheless sets a new standard for all World War 2 games to come.

May 14 2003

After countless rumors, Half-Life 2 is officially announced and previewed at E3. Showing off the years of work that went into the Source engine, many a jaw hits the floor as Gabe Newell previews one of the first games ever to use authentic-looking “real world” physics and lighting. If that wasn’t enough, the wait will be mere months with a September, 2003 release date. The entire industry is psyched, let alone fans the world over.

June 14 2003

The Half-Life 2 Tech demo is released as a stream-able video through Steam. Source

September 11 2003

A German hacker named Axel Gembe breaks into Valve’s secure network undetected and steals pieces of source code as well as small sections of Half-Life 2 which had been shown at E3. The leak is only noticed when copies of it surface on various pirate sites, much to the shock of Valve developers.

September 12 2003

Steam is released as a non-beta client. Right away users see that it is much more than a simple distribution service, also covering game registration, multiplayer servers and anti-cheat protection. Users also notice that once Steam is installed it acts as an unavoidable launch pad and background program to their Valve games. A general sense of concern begins to rise amongst certain parties…

September 30 2003

The concern over Steam is nothing compared to the pure rage that unfolds as the last day of September comes and goes without so much as a peep from Valve on the status of Half-Life 2.

October 2 2003

Gabe Newell posts an apologetic letter on HalfLife2.net explaining publically for the first time that Valve was hacked and small chunks of code as well as levels from Half-Life 2 were stolen, which is why the release has to be pushed to early 2004. He fails to explain why the leaked information shows a very incomplete game, small chunks or not, or how the stellar A.I. shown in E3 video appeared to have been scripted, or even how such a theft could delay a game that was set to be released in mere weeks anyway. He also fails to explain why the password to the secure Valve network was simply “GabeN”. In any event, the break-in is so shocking and unprecedented that the gaming world simply gives Valve a pass.

March 21 2004

Counter-Strike: Condition Zero is released, a stand-alone version of the original mod developed by third-party Turtle Rock Studios, with additional maps and a single-player campaign, which is really just the same multiplayer maps populated with bots.

April 1 2004

Half-Life 2 is delayed once again, this time as far ahead as September 2004, a full year past its initial release date. Kevin “Fragmaster” Bowen, who had inside information he had been withholding due to a non-disclosure agreement, lets loose in a long, infamous rant/resignation letter posted on the PHL forums. He claims that Valve had been deceptive in its marketing and that the first delay had nothing to do with the theft of the source code and everything to do with the fact that Half-Life 2 simply wasn’t finished yet.

May 10 2004

In the face of mounting accusations and rumors, Gabe Newell admits that the major delays in the release of Half-Life 2 had little to do with the leak, and that the company was being unrealistic about its progress from the first E3 announcement. He goes on to confirm a 2004 release date is absolutely definite, regardless.

August 11 2004

To give players an early taste of the Source engine first hand, Valve releases Counter-Strike: Source. In the months leading up to Half-Life 2’s release, thousands of players enjoy the thrills of realistically knocking over barrels and shooting up fruits and vegetables and other small props. For reasons unknown, Counter Strike: Source never takes over Counter Strike 1.6 in terms of popularity. It is also at this time that the full extent of Steam is unveiled, in particular that it will be required to play Half-Life 2 and all other Valve titles from this point on. Some gamers are so incensed that they vow never to buy a Valve product again, no matter how good it is.

September 20 2004

Instead of a release, fans are let in on the details of a legal battle between Valve and Vivendi Universal Games, who had recently bought out Sierra On-Line and thus had an exclusive distribution contract with Valve. The lawsuit revolves around Steam, which VUG argued would undercut its retail sales, particularly to Asian cyber cafes. The release is delayed once again, this time indefinitely.

November 16 2004

Much to the shock of many, Half-Life 2 is actually released after many were starting to think it would be the next Duke Nukem Forever. For some, Steam servers crash from so many players trying to authenticate and start up the game at the same time, while others are able to get right into City 17 without a hitch. Despite its sordid release date fiascos and Steam’s technical hiccups, no one can deny the achievements of Valve in creating this game, which goes on to be another bestseller, snags 35 Game of the Year Awards (it had tough competition against Doom 3) and even a Guinness World Record for “Highest Rated Game.” Many publications claim, “It’s fitting that the first game that could knock Half-Life off its pedestal of six years was its own sequel.”

November 23 2004

Valve through Prima Games publish “Half-Life 2: Raising the Bar” authored by David Hodgson. Available in both hardback and paperback the book is a collection, comprised of images, notes on game design, game development, cut concepts and employee interviews. The development of Half-Life, Team Fortress, Day of Defeat, Counter-Strike, Counter-Strike: Source and Half-Life 2 are covered in detail. The book is no longer in print and has become something of a collectable.

April 24 2005

Students at the DigiPen Institute of Technology, a tech school for aspiring video game developers, release Narbacular Drop to little public notice. It does not pass by Gabe Newell, however, who hires the students right out of school to develop a more professional version of their game. Meanwhile the Steam catalog begins to expand wildly beyond Valve games, becoming a true pioneer on the digital distribution front.

October 27 2005

Showing off the Source engine’s modular upgradeability, Half-Life 2: Lost Coast, a single-map mission, is released as a technical demonstration of new high dynamic range rendering.

December 26 2005

Day of Defeat gets a Source engine remake, making special use of several post-processing visual filters to give it that gritty, 1940s war film look.

May 11 2006

At the E3, Gabe Newell unveils the latest work on Team Fortress 2 after six years of silence. Hardcore Team Fortress Classic fans are outraged by the total 180 taken on its design, many equating it to a “kiddy” Disney-Pixar cartoon. Also unveiled is Portal, the professional retooling of Narbacular Drop and an interesting departure from previous Valve titles.

June 1 2006

Half-Life 2: Episode One is released, the first of an anticipated trilogy of expansion packs that serve as a sequel to Half-Life 2. It contains improved Source features and a lot more of Alyx Vance fighting by your side. Critics and fans love it, yet lament the long stretches that will apparently be in-between releases.

November 20 2006

Turtle Rock Studios announces development of a new zombie survival game called Left 4 Dead, to be made on the Source engine.

September 13 2007

The Steam Community officially launched and provides users with the ability to check stats, plan events, access this information in and outside of a game as well as a VOIP that is part of the Steam overlay that will work in and out of game.

October 10 2007

The Orange Box, featuring Half-Life 2: Episode Two, Portal and the long-awaited Team Fortress 2 is released to great acclaim and several more awards. It receives an unprecedented advertising campaign for a Valve release, and thanks in part to a simultaneous release on the Xbox 360, it expands the Valve brand further into “casual” gamer audiences than ever before.

October 11 2007

Gabe has a small rant about how hard it is to develop on the Playstation 3

January 10 2008

Valve acquires Turtle Rock Studios specifically to take over the development and release of Left 4 Dead. Spokesman Doug Lombardi also confirms that Portal 2 is already in the works, and that Half-Life 2: Episode Three will take longer than the previous two episodes to develop because it will be a much longer, much more epic game than any installment prior, and that in no uncertain terms it will be the conclusion to the Half-Life series as we know it, “tying up all of the loose ends.” Many fans are quick to try to read between the lines and go into a deep denial about their beloved series eventually coming to a close sooner rather than later.

January 29 2008

Valve Release Steamworks, which is a feature rich publishing platform for developers hoping to release their games on Steam. According to Valve it is,

June 1 2009

Left 4 Dead 2 is announced at E3 2009 and almost immediately is met with hostility from “fans”. A boycott is setup receiving a huge following of around 37,000 people within the first month. The groups premise was based on…

“The announced content of Left 4 Dead 2 does not warrant a stand-alone, full-priced sequel and should instead become updates (free or otherwise) for Left 4 Dead“

June 9 2009

Valve respond to the criticism.

“Looking back, was the Orange Box a rip-off?” He said, on initial complaints at having to “buy” Half-Life 2 again in the compilation. “Give us a fair shake on this, read more about it, find out about it, we’ve already let people play it [at E3]… After that, if you want to vent, post to the forums. We do read them, we read all the forums.”

GabeN address’s E3 through the Playstation 3 briefing only to announce Portal 2, and to go back on his previous rant about developing for the Playstation 3.

When the PlayStation 3 was introduced, I was the one of the platform’s biggest critics. However, Sony Computer Entertainment has proved that the PlayStation 3 is the most open platform of all the current generation consoles and has worked extremely hard to make the platform the most desirable for consumers and developers. As such, we are delighted to announce Portal 2 for the PlayStation 3 and believe the Steamworks support included will make it the best console version of the game.
