Here's a break down of what's going on in the TF2 VR mode update:
Team Fortress 2 will have support for Oculus Rift in "a couple of weeks."
Windows only for now, but Valve will release Linux and Mac support asap.
Can play on any TF2 server.
Joe will be giving a presentation next week at the Game Developers Conference, titled "What We Learned Porting Team Fortress 2 to Virtual Reality", so we'll have the chance to get an even better look.
Speaking with Engadget, Valve programmer Joe Ludwig revealed that they're releasing the first official Oclulus Rift title on Windows, and it will "be available some time within the next couple of weeks." Of course, the consumer version of the Rift still has no release date, so this is only for those with the SDK but it's good to know this is getting the field experience.
