Valve, creators of best-selling game franchises (such as Counter-Strike, Dota 2, Half-Life, Left 4 Dead, Portal, and Team Fortress) and leading technologies (such as Steam and Source), today announced over one dozen Steam Machine designs now in production from leading manufacturers and targeted for release in 2014. The lineup of Steam Machines announced today offers a wide variety of price and performance options made possible by the Steam Machine's open design, with systems starting as low as $499 and top end systems rivaling today's bleeding edge gaming PCs.

Every Steam Machine includes an innovative Steam Controller designed for use with a wide variety of game genres, and is powered by the SteamOS, a custom OS built atop Linux. "The first generation Steam Machines offers something for every gamer, which is a critical part of extending Steam into the living room," said Gabe Newell of Valve. "With over 3,000 games and more than 65 million gamers on Steam, it's important to offer gamers a variety of Steam Machines that allow them to select what makes the most sense for them."

Next year PC maker iBuyPower is planning to embrace Valve's Steam OS and release its own Steam Machine. Seen below in prototype form, iBuyPower's upcoming Steam OS-running 'console' looks a bit like a PlayStation 4, design-wise, and packs an AMD processor (likely an APU) and AMD Radeon R9 270 graphics card (in contrast, Valve's own Steam Box prototypes have Intel CPUs and NVIDIA GPUs), and a 500 GB hard drive.

The iBuyPower Steam Machine also has a glossy white chassis with a customizable light bar, and is set to cost $499 (as much as an Xbox One). The Steam Controller wasn't mentioned but it's likely at least one will be bundled.

People looking forward to the big "Steambox" announcement were met by an anticlimax. Valve announced its own operating system for PC gamers, which turns any PC into a "Steambox." Simply named Steam OS, the operating system is a highly modified Debian Linux stripped to bare, with all its non-essentials tossed out, and proprietary multimedia CODECs added, along with fonts, runtime environments, and in-built drivers for popular GPU, sound card, and gaming-peripheral brands. In essence, there's everything in the operating system for PC gamers, and then some.

Steam diversified from distributing PC games to non-gaming PC software, and Valve plans to take that further by doing groundwork for its very own living room content-delivery platform to compete with the likes of Xbox One. Since Steam OS can be deployed onto x86-based PCs as tiny as an Intel NUC, it stands more than a half chance. Its baby-steps are taken with In-home Streaming, a feature that lets you stream content off a PC or Mac in your house. You can share games in your account with others in your family, and close friends, using the recently-announced Family Sharing feature. You get content-blocking features and restricted-accounts. You also get media-player software that lets you organize and play back music and videos in most open- and proprietary formats. You should be able to install popular web-browsers like Google Chrome. Steam OS is competitively priced against Windows 8.1 and OS X 10.9, at $0. Did we tell you that some of its icons look like companion cubes? Just kidding.

SteelSeries, the worldwide leader in professional grade gaming peripherals along with Valve, developer of Dota 2 and creator of The International Tournament, today announced the Siberia v2 Illuminated Gaming Headset Dota 2 Special Edition which features an exclusive in-game item, Scythe of Vyse for Nature's Prophet.

In addition to the new headset, SteelSeries will also roll out two new SteelSeries QcK+ mousepads featuring character artwork from the game. The Siberia v2 Dota 2 Edition headset lets the player experience the non-stop excitement of the game while enjoying an incredible soundscape, lightweight over-the-head suspension design and the ability to customize what you're hearing through an easy-to-configure software suite. Red LED illumination on the outside of each earcup can also be customized to exact user specifications and profiles via the SteelSeries Engine. At an MSRP of $119.99, the headset is equipped with large, premium driver units for the loudest and clearest sound while its circumaural earcups are wrapped in soft leather for comfort and increased passive noise reduction.

Valve, creators of best-selling game franchises (such as Counter-Strike, Half-Life, Left 4 Dead, Portal, and Team Fortress) and leading technologies (such as Steam and Source), today introduced the Steam Community Market, now in Beta with Team Fortress 2.

The Community Market is designed to expand the Steam Economy beyond trading. Players are now enabled to buy and sell in-game items with other players for Steam Wallet funds.

"With over a half million trades made every week, the trading system has been very successful," said Tony Paloma of Valve. "Extending game economies beyond trades and giving players a way to turn gameplay into funds for new items and games is a key component for moving that success forward."

Steam for Linux targets Ubuntu, and the company plans to launch the platform with Left 4 Dead 2 with SteamPlay enabled, porting other Valve titles later.

This second wave of titles was originally targeted to include at least 10 titles. Given the number and quality of games submitted, and the ship date of many of the top-ranking titles, the decision was made to increase the size of this group.

Steam Greenlight is a new platform feature that enlists the community's help in selecting some of the next games to be released on Steam. Launched on August 30, Greenlight allows developers and publishers to post information and media about their game in an effort to convince Community members that their game should be released on Steam.

The first set of titles to launch via Greenlight will be released independently in the months ahead (as they are varying stages of completion).

"The Steam community rallied around these titles and made them the clear choice for the first set of titles to launch out of Greenlight," said Anna Sweet of Valve. "Since launch, hundreds of titles have been submitted, with more coming in every day. We expect to be announcing more titles coming to Steam via Greenlight soon."

With the press of a button, Steam displays a new full-screen user interface optimized for readability and interaction on TV. Big Picture has been designed to be used with a traditional game controller, while also fully supporting keyboard and mouse input.

Valve, creators of best-selling game franchises (such as Counter-Strike, Half-Life, Left 4 Dead, Portal, and Team Fortress) and leading technologies (such as Steam and Source), today announced the launch of Steam Greenlight, a new platform feature that enlists the community's help in selecting some of the next games to be released on Steam.

Valve, creators of best-selling game franchises (such as Half-Life and Team Fortress) and leading technologies (such as Steam and Source), today announced Counter-Strike: Global Offensive is available for pre-purchase worldwide.

All players who pre-purchase on Steam receive a 10% discount and gain early access to the beta on August 14th.

Valve's hit online multiplayer game, Left 4 Dead 2, which was recently ported to Ubuntu along with the Steam client, is found to play faster on the platform than even Windows. The game generates higher frame-rates on Ubuntu with the new OpenGL renderer for Source engine than the Direct3D renderer it uses on Windows.

The disclosure comes as part of Valve's ongoing efforts to optimize the Source engine to the Linux platform, following which, it plans to port more of its game franchises, such as Half Life, Counter Strike, Team Fortress, and Portal. The games will be available on Ubuntu with SteamPlay, allowing users who already own a license for the Windows or Mac OS X versions to simply download and play the game on Ubuntu, without any purchases.

Valve announced porting of its Steam content-distribution platform, Source game engine, and the smash-hit multi-player game title Left 4 Dead 2 (L4D2), to Ubuntu (Linux). The port isn't exactly straightforward, as code has to be rewritten for OpenGL. Valve already accomplished most of this, with its Mac OS X port, which uses the same API.

Valve is targeting just one distribution at this time, to minimize "optimization" overheads. Derivatives such as Mint could run the platform just fine. Valve's immediate goals are to get the Steam client to work on Ubuntu with full functionality, launching Steam for Linux with L4D2 (thanks to SteamPlay, gamers with L4D2 on Windows can play it on Ubuntu without additional purchases); and optimizing L4D2 to get additional frame-rates on Ubuntu. Valve is also work to get its other titles ported to Ubuntu.

Valve, creator of best-selling game franchises (such as Counter-Strike, Half-Life, Left 4 Dead, Portal, and Team Fortress) and leading technologies (such as Steam and Source), today announced the open beta release of Source Filmmaker (SFM), for free, to everyone.

The SFM condenses the production pipeline of an animation studio down onto a single gaming PC. To help the community get started, the SFM includes all assets from Team Fortress 2 along with assets from two of the "Meet the Team" short films.
