Lol, well to me anyways.
Start a 1 player game and verse the gray guy. Hold space bar to slow down time super slow motion. Left/Right: move left and right. Up is jump, down is usually to dropkick after jumping.
Try lots of combos like up -> down, this will do that matrix dodge the bullets thing. Run to him press the opposite direction for some flying kicks and all.
300 bullets mode: shift to bring out gun. Ctrl to shoot.
Its crazy fun for wasting time :krazy:.
