A comprehensive digital archive celebrating 30 years of revolutionary games, transformative technology, and the enduring legacy of one of gaming's most influential companies.
Est. 1996
From a small Kirkland, Washington startup to one of the most valuable private companies in the world — Valve's story is inseparable from the story of modern PC gaming.
Valve Corporation was founded on August 24, 1996, by Gabe Newell and Mike Harrington, two former Microsoft employees. Newell had spent 13 years at Microsoft, rising to become a producer on the first three versions of Windows. Harrington similarly had a long tenure at Microsoft. Both left with the financial security and technical expertise to pursue an ambitious vision.
Their initial capital came largely from Newell's Microsoft tenure. The company was incorporated in Washington state and headquartered first in Kirkland, later moving to Bellevue, Washington — where it remains today in a converted office building.
Valve licensed the Quake engine from id Software and spent two years building their debut title, Half-Life, which would go on to revolutionize first-person shooters and set the template for narrative-driven action games.
Valve is famously structured as a "flat" organization with no traditional management hierarchy. Employees are empowered to choose their own projects and move their desks — literally on wheels — to join teams working on problems they find compelling. This radical philosophy is documented in Valve's famous employee handbook, which was leaked publicly in 2012.
This approach has produced some of the most beloved games in history, but has also been criticized for allowing projects to languish or disappear entirely, as no single person is accountable for shipping any given product.
Gabe Newell and Mike Harrington incorporate Valve, LLC in Kirkland, Washington. They license the Quake engine from id Software and begin work on their first game.
Half-Life launches to universal acclaim, winning over 50 Game of the Year awards. It revolutionizes FPS storytelling and spawns one of gaming's most beloved franchises.
Valve acquires the rights to Counter-Strike (originally a Half-Life mod by Minh "Gooseman" Le and Jess "cliffe" Cliffe) and Day of Defeat, establishing a pattern of fostering and purchasing community mods.
Valve launches Steam, a digital distribution platform initially unpopular with players. Over time it becomes the dominant PC gaming marketplace, fundamentally changing how games are sold and updated.
Half-Life 2 releases alongside the Source Engine, introducing groundbreaking physics simulation. The game wins multiple GOTY awards and is widely considered one of the greatest games ever made. Counter-Strike: Source launches simultaneously.
Valve releases The Orange Box, one of the most critically acclaimed game compilations of all time, including Half-Life 2, Episodes 1 & 2, Portal, and Team Fortress 2. Portal becomes a cultural phenomenon.
Left 4 Dead launches, pioneering the cooperative survival horror genre with its "AI Director" — an adaptive difficulty system that became widely influential.
Steam opens to Mac (2010) and Linux (2012). Steam Greenlight launches, allowing community curation of new titles. Valve begins aggressively expanding Steam's catalogue and features.
Dota 2 exits beta, becoming one of the most played games on PC and home to The International, one of esports' largest prize pool tournaments — reaching over $40 million by 2021.
Valve announces SteamOS (a Linux-based gaming OS) and Steam Machines — living-room gaming PCs. While Steam Machines underperform commercially, the technology lays groundwork for the Steam Deck.
Counter-Strike: Global Offensive becomes free-to-play with Battle Royale mode "Danger Zone" added. The game surpasses 1 million concurrent players and becomes one of the most-played titles on Steam.
Half-Life: Alyx releases as a landmark VR-exclusive title, proving the viability of premium VR games and ending a 13-year absence from the Half-Life universe. Powered by Source 2 engine.
The Steam Deck, a handheld gaming PC, begins shipping. It runs SteamOS and can play the vast majority of the Steam library. It becomes Valve's most commercially successful hardware product and spawns a new handheld gaming PC category.
CS2, built on Source 2, permanently replaces CS:GO. The update brings sub-tick servers, overhauled graphics, and completely redesigned maps while maintaining CS's core gameplay.
Valve's hero shooter Deadlock enters open playtesting. The Steam Deck OLED model launches in November 2023 with improved battery, display, and WiFi. Valve continues iterating on all major platforms.
Valve hired Minh Le ("Gooseman") and Jess Cliffe, acquiring the rights to Counter-Strike. The mod had become one of the most popular online games in the world within months of release.
Valve acquired key developers who would later form Turtle Rock Studios, responsible for Left 4 Dead. The relationship would later dissolve as Turtle Rock became independent again.
Valve hired IceFrog, the anonymous lead developer of Defense of the Ancients (DotA), a Warcraft III mod. This led directly to Dota 2, one of the most successful games in Valve's history.
Valve partnered with HTC to develop the Vive VR headset, with Valve providing SteamVR platform software and room-scale tracking technology ("Lighthouse").
Valve released its own fully first-party VR hardware: the Valve Index headset and Knuckles (Index) controllers, demonstrating Valve's full vertical integration in the VR space.
Valve's Steam Workshop infrastructure has become one of gaming's largest mod distribution platforms, with thousands of games supporting community-created content worth billions in aggregate value.
The People
The visionaries, engineers, and creative minds who built Valve into a global gaming powerhouse.
Co-Founder & President
Born in 1962, Newell attended Harvard before dropping out to join Microsoft, where he spent 13 years as a producer on Windows 1.0, 2.0, and 3.0. Affectionately known as "Gaben" by fans, he co-founded Valve in 1996. Under his leadership, Valve has produced landmark games and built Steam into the dominant PC gaming platform. Known for his candid communication with the community, occasional Reddit AMAs, and personal appearances at events.
Co-Founder (1996–2000)
Also a former Microsoft engineer, Harrington co-founded Valve alongside Gabe Newell in 1996. He played an integral role in the development of Half-Life and the establishment of Valve's technical foundations. Harrington departed from Valve around 2000, shortly after Half-Life's enormous success, to pursue other interests. He is significantly less public than Newell.
Lead Designer
Robin Walker co-created Team Fortress as a Quake mod in 1996 while studying at Bond University in Australia. Valve hired him, and he led the design of Team Fortress Classic, Team Fortress 2, and has been a key contributor to Valve's design philosophy. Walker is known for his detailed public commentary on game design decisions.
Portal Lead Designer
Kim Swift led the team that created Portal while a student at DigiPen Institute of Technology. The prototype, "Narbacular Drop," impressed Valve so much that the entire student team was hired. Swift served as lead designer on Portal and Left 4 Dead, before leaving to work at Airtight Games and later Amazon Game Studios. Portal remains one of gaming's most beloved puzzle games.
Writer (2005–2017)
Chet Faliszek joined Valve in 2005 and co-wrote Portal 2, Left 4 Dead, Left 4 Dead 2, and contributed to numerous Valve projects. He was one of Valve's most visible public-facing personalities. He departed in 2017 and has since worked on VR projects and other game development ventures. Known for his witty writing and commitment to cooperative game design.
Writer — Portal, Portal 2
Erik Wolpaw joined Valve in 2005 after a career as a games journalist at GameSpy. He co-wrote Portal, Portal 2, and worked on Half-Life: Alyx. Wolpaw is responsible for much of GLaDOS's iconic dialogue. He briefly left Valve but returned as a contractor. His sharp, dark humor defines the Portal series' voice.
Narrative Lead, Half-Life
Marc Laidlaw was Valve's primary narrative writer from 1997 to 2016, responsible for the storylines of Half-Life, Half-Life 2, and both episodes. A published science fiction author before joining Valve, he created the world, characters, and lore of the Half-Life universe. After departing, he published "Epistle 3" — an unofficial synopsis of Episode 3 — which the community received as the closest thing to the unreleased conclusion.
Dota 2 Lead Designer
Known only by pseudonym, IceFrog was the primary developer of DotA Allstars (the Warcraft III mod) before being hired by Valve around 2010 to lead development of Dota 2. Their identity has been one of gaming's most persistent mysteries. Under IceFrog's direction, Dota 2 became one of the most strategically complex and lucrative competitive games in history.
Graphics programming legend who worked at id Software before joining Valve, where he worked on graphics and VR technology. He later joined Oculus/Meta as Chief Scientist, but his Valve work was instrumental in the VR research pipeline leading to SteamVR.
Valve's in-house composer responsible for the iconic soundscapes of Half-Life, Half-Life 2, and Portal. His atmospheric, industrial scores defined the sonic identity of Valve's early franchises before departing in 2012.
Long-serving VP of Marketing at Valve, responsible for many of the company's unconventional marketing campaigns and public communications. A key public-facing voice for the company through much of its history.

The Platform
Launched in 2003 as a frustrating update mechanism, Steam grew into the world's dominant PC gaming platform — reshaping how games are discovered, distributed, and experienced.
Steam was born out of necessity: Valve needed a way to push updates to Counter-Strike without relying on third-party patching systems. The initial 2003 launch was notoriously rocky — players criticized it as slow, invasive, and unnecessary. The platform required an internet connection, which was controversial at the time.
The turning point came with Half-Life 2 in 2004, which required Steam for activation. This controversial decision forced millions of players onto the platform. Over the following years, Valve added features — achievements, community profiles, friends lists, the Steam Market, Workshop — that transformed Steam from an update tool into a social gaming platform.
Steam Greenlight (2012) opened the platform to indie developers. Steam Direct (2017) replaced Greenlight with a simpler submission process, leading to a massive expansion of available titles. By 2023, over 14,000 games were released on Steam annually.
Steam's dominance in PC gaming distribution has been both celebrated and scrutinized. Its 30% (now 20–30% tiered) revenue share became the industry standard, replicated by Epic Games Store, GOG, and others. Steam enabled the indie game renaissance by providing global distribution to small developers without requiring a publisher.
Critics have noted Steam's market power — some argue it functions as a de facto monopoly on PC game distribution. Epic Games launched the Epic Games Store in 2018 as a direct competitor, offering a 12% cut and exclusive titles to attract developers.
Launched in 2011, Steam Workshop enables players to share and install user-created modifications, maps, skins, and content directly through the Steam client. Thousands of games support Workshop integration. Valve pioneered the concept of monetized Workshop items with Team Fortress 2, later expanded to Counter-Strike and Dota 2, creating an economy worth hundreds of millions of dollars.
Steam's community features include discussion forums, player profiles, achievement tracking, game reviews, screenshot sharing, and the Steam Community Market — a platform for buying and selling in-game items. Community hubs provide per-game discussion boards, guides, and artwork galleries. The system hosts hundreds of millions of user reviews.
Released February 2022, the Steam Deck is a handheld gaming PC running a customized SteamOS 3.0 (Arch Linux-based). It features an AMD APU, 7-inch touchscreen, and compatibility with the vast majority of the Steam library. An OLED model launched in November 2023. The Deck revitalized Valve's hardware aspirations after the Steam Machine era.
SteamVR is Valve's virtual reality platform supporting headsets from multiple manufacturers including HTC Vive, Valve Index, and many others. It provides the underlying software stack for PC VR gaming and pioneered room-scale VR tracking with the "Lighthouse" base station technology co-developed with HTC.
SteamOS is Valve's Linux-based operating system, currently on version 3.x (based on Arch Linux) for the Steam Deck. The original SteamOS 1.0 (2013, Debian-based) was designed for Steam Machines. SteamOS includes Proton, a compatibility layer based on WINE that allows Windows games to run on Linux, dramatically increasing the playable catalogue.
Valve's seasonal sales events — Summer Sale, Winter Sale, Autumn Sale, Spring Sale — became cultural phenomena, with players joking about spending far more than intended. The sales have been credited with normalizing digital game discounts industry-wide and driving enormous revenue spikes for developers on the platform.
Physical Products
Valve's hardware ventures — from living room experiments to the portable gaming PC that defined a category.
Technology
Valve's proprietary game engines have powered decades of landmark titles and influenced the broader industry.
GoldSrc (sometimes "GoldSource") was Valve's first proprietary engine, heavily derived from id Software's Quake engine with significant modifications to rendering, entity system, and scripting. It powered Half-Life (1998), Team Fortress Classic, Counter-Strike 1.x, Day of Defeat, and Deathmatch Classic.
Half-Life, Opposing Force, Blue Shift, Team Fortress Classic, Counter-Strike, Day of Defeat, Deathmatch Classic, Ricochet, CS: Condition Zero (partial)
Source Engine debuted with Counter-Strike: Source and Half-Life 2 in 2004. It introduced real-time physics through the Havok physics engine, advanced facial animation (the "face poser" system), HDR lighting, and the Hammer editor for level design. Source was continuously updated through 2013 and beyond.
HL2 & Episodes, Portal, Portal 2, TF2, L4D, L4D2, CS:S, CS:GO, Dota 2 (partial), Alien Swarm, and hundreds of third-party titles
Source 2 is Valve's current-generation engine, first publicly used in Dota 2 (2015 update) and Dota Underlords. It was the engine for Half-Life: Alyx, Counter-Strike 2, and the forthcoming Deadlock. Source 2 features a Vulkan/DirectX 12 render path, physically based rendering (PBR), advanced lighting, and improved tools.

Recognition
Valve's impact on gaming has been recognized by critics, industry bodies, and the community for decades.
Valve's fingerprints are on virtually every corner of modern gaming. Half-Life's environmental storytelling — delivering narrative without cutscenes — became the template for a generation of first-person games. Portal's physics-based puzzles spawned an entire genre. Team Fortress 2's class-based design influenced everything from Overwatch to Valorant.
Steam democratized game distribution, making it possible for a two-person studio to reach millions of players globally without a publisher. The Workshop model showed that community modding could be a revenue-generating ecosystem rather than just a hobby.
Counter-Strike is widely credited as the founding competitive multiplayer game — the direct ancestor of all modern tactical shooters. Dota 2 and the DotA genre gave birth to the MOBA category, which became briefly the world's most-played genre.
Valve's famously flat structure — no managers, no formal hierarchy, employees choosing their projects — has been both praised and criticized. It has produced remarkable games and is held up by business schools as an example of radical organizational design. Gabe Newell has attributed Valve's success largely to this structure, arguing it attracts the most talented, self-directed people.
Critics, including former employees, have noted that the flat structure can create informal power structures around influential employees, make it difficult for newer hires to get traction, and contribute to projects being abandoned when employee interest shifts. This is often cited as an explanation for long development silences on major franchises.
Despite this, Valve remains one of the most profitable private companies per employee in the world, estimated at several million dollars in revenue per employee.
