Ever since Oculus Rift was unveiled, modders have been working on unofficially adding VR support to many PC games, including Valve's classic Half-Life 2. However, Valve has been experimenting with VR as well, and plans on launching an official "VR Mode" for its popular free-to-play shooter, Team Fortress 2.

Speaking to Engadget, Valve's Joe Ludwig says that Team Fortress 2 is the first Valve game to get VR support because the community is used to the game's frequent updates. "We use it as a place where we run experiments," Ludwig said.

Of course, Valve's catalog has a number of first-person games that would be ripe for a VR conversion, and that's something Valve is "interested" in. Team Fortress 2 may be the first game to get VR support from the studio, but it likely won't be the last. "We've played a bit in Left 4 Dead; we've played a bit in Half-Life 2. We haven't taken any of those other games to the point where they're anywhere close to being ready to be shipped; we've just sort of experimented with head tracking a little bit."
