Urban Chaos: Riot Response Cheats
when you have the cheat ULTIMATEPOWER in, go into a level and pick the assault rifle, shoot a bomb then quickly press the shield button. dont hold it, just press and release! then shoot the bomb again and repeat. this way you can shoot 15 bombs in 10sec and kill just about everything. its not a glitch so you do it whenever you need it but you have to do R2 then L1 then R2 then L1 repeat.
