Oculus have just had quite the announcement for gamers, stating that they have shipped a beta for Half-Life 2 that now includes Oculus Rift support. In order to get it working, check out the post on Oculus' forum.
This is some incredible development for Oculus, who have seen support for Team Fortress 2, another Valve title, and now the inclusion of Half-Life 2 is forming an interesting relationship between the VR headset company and Valve. Do I smell a buyout by Valve? You heard it here first, folks!
