Press A or D (J or L) to turn (turning will slow you down and can be used as a brake). Press S (K) to use Sniper Rifle Press or hold W (I) to use Machine Gun Press Q (U) to cycle between the different aiming types (Spin, Aim in front of you and Aim behind you) Tips: it's good if you can get behind your enemy because they can't hit you with their sniper rifle. Slow down to regenerate health (you regenerate health 2x quicker when it's below 50)
