Valve revealed a number of things at GDC 2015, unfortunately none of them were named Half Life 3, and none of them were actual games. Valve has indeed been working on a number of things however.
Source 2 Engine: First off, Source 2 has finally been revealed. The successor to the popular Source Engine that Valve has been using on a number of games, which include Portal, Half Life 2, and Left 4 Dead, will apparently focus on many creative tools.
“Given how important user generated content is becoming, Source 2 is designed not just for the professional developer, but enabling gamers themselves to participate in the creation and development of their favorite games,” according to Valve. The Engine will also be free to content developers.
Source 2 rumors had been flying for a while now. The official announcement from Valve could mean that they’ll actually have a game coming out of their studios in the near future to showcase the tools. While many have been holding their breath for a continuation of the Half Life series in recent years, speculation has also suggested that Left 4 Dead 3 may be Valve’s next big game.
Lighthouse VR: Last week Valve announced that they would have big things to share at GDC. Over the last couple of days the picture is beginning to become clearer about Valve’s VR plans. Valve doesn’t appear to be jumping into the VR headset game anytime soon, but what they have been developing, they’re calling “Lighthouse,” tracking technology that allows headsets to connect to other devices, allowing it to have room scale tracking.
Steam Machines: It appears that Steam Machines will be ready for consumers this November. The idea behind Steam Machines is for purchasers to get more bang for their buck over consoles.
Steam Link : Steam Link is a new product from Valve that is designed to extend the Steam experience to any room in the same home network. Steam Link supports 1080p at 60Hz with low latency and will retail this November for $49.99.
Steam Controller: Steam controller will be available with Steam Link this November for an additional $49.99.
