Can anyone explain the controls???
cause ive only seen this played once

W, S, A, D - movement keys
E - use key (open doors or switches or ammo from armory or build)
R - reload or leap as skulk, or blink as fade
F - flashlight or alien hive sight
Space - jump
Right click - menu
Left click - shoot
Mouse wheel - switch weapons

Good luck, hope I didn't forget any of the important keys
