It seems that the Oculus rift has finally found what it was created for.
Hawken is a game that at its core is basically Mech warrior. You wonder around the map destroying other robots for reasons you don't even care about. Its free to play so even without a rift its worth grabbing.
What makes this ideal for the Oculus rift is that it is played from inside the cockpit of the mech. Making you fully immersed in the game.
All you need now is someone to hit you with a pillow when you take damage.
Oculus Rift Support: Fully immerse yourself in mech battles with gameplay support for the Oculus Rift.
