Valve has announced that an experimental Virtual Reality mode will be added soon to Team Fortress 2 as a free update. Anyone with an Oculus Rift Developer Kit will be able to use their device to play all of Team Fortress 2 on the PC. All game modes and classes are supported with the new Virtual Reality mode.
In addition to gaining access to the new Virtual Reality mode, owners of the Oculus Rift will also be granted a unique Oculus Rift in-game hat. Steam codes to redeem for this item will be sent out by Oculus.
