vrTANKS is a Unity game I have been working on for the Oculus Rift (a Virtual Reality headset).
It is an arcade-style tank simulator. Your goal is to destroy as many enemy tanks as you can before being destroyed yourself. Pilot your tank using an Xbox controller or keyboard – tank weapons fire in the direction you are looking.
This is a work in progress, and I hope to have a complete experience together in time for the commercial release of the Oculus Rift. See my blog entry, or the Oculus Dev forum post for more information.
Using a similar game mechanic to vrTANKS, I created a simple demo called Great Scott, Asteroids! – A virtual reality asteroid shooter concept that I submitted to the Oculus VR Game Jam
