I did recently play COD, but let's make this interesting. The last game I played was C.R.U.S.H., wherein you don't actually have any weapons, but you have one (and only one) ability that you sometimes use offensively.
You have the ability to make the 3D enviroment into a 2D level depending on how the camera is angled when you "crush". So horizintal lines on a wall in 3D become platforms in 2D. Bricks are solid objects in 2D so anything you "crush" against it will die.
So yeah, I think I'll be good.
