Player 1: 
W + S to move up and down
Space to shoot, hold space to charge up
E to shield
Q to EMP

Player 2: 
Up + Down arrows to move up and down
M to shoot, hold M to charge up
N to shield
B to EMP

Mechanics:

There is a shield cooldown, charged up bullets do three damage and can break shields, normal bullets do one damage and cannot penetrate shields. Charged up bullets also move faster than normal bullets. Health regenerates after ten seconds. Moving uses fuel, stand still for a second to regen it. P pauses and un-pauses the game. Q and B use EMP blasts that disable shields and stop them from shooting, however you can only use it once per match.
