Kind of works. You have to press down on the joystick for the tank to turn in the direction you want. For the menu, you have to press trigger and click down on the joystick as well. I had to refund because above problems, made it too difficult to play. Turning is just too difficult with that Oculus control scheme....

Would probably make more money that way.

It doesn't look like it uses a voxel based engine.
