I really wasn't planning on buying this game and now I wish I hadn't! I am aware that the game is based on the confusion and pointless mayhem one would associate with a riot but after playing for a short period the game needs some direction. Once you get the past the initial fun of hitting someone in the head with a garbage can or firing a grenade into a crowded mall there seems to be little else of interest. The missions in Revolution mode are repetitive and advancement in Chaos mode depends on rapidly pressing 2 buttons. Rent--don't buy!
