The game features a ballistic bullet mechanic where you can charge each shot to have a higher exit velocity. Since only one player bullet can be visible at a time, the damage that can be done in any given timespan is severely limited, necessitating hitting multiple targets in one shot for best efficiency.

Quite strikingly, this game is plagued by extreme lag, slowing in-game time down significantly and contributing to about 80% runtime of the entire movie (about 4 lag frames per normal frame).
