Not that bizarre actually. I played tens of hours of Serious Sam "local coop". Basically one player plays with arrow keys and mouse, the other player plays with WSAD and lookup/lookdown button. The general strategy is for the WSAD player to clear everything on the ground level, while the mouse player is killing stuff on higher ground and doing other precision shots.

No I mean two people playing one playable character. One running the legs and the other running the arms.
