SSShooter

One player has a keyboard and mouse, the other a controller (I use a PS4 controller).

Keyboard controls: WASD to move, MOUSE to look around, Q to decrees gravity for yourself, SHIFT to run, and MOUSE 1 to shoot.

Controller controls: LEFT JOYSTICK to move around, RIGHT STICK to look around, R1 to decrease gravity for yourself, L1 to run, and R2 to shoot.
