So why am I giving Prototype only a 7.5 out of 10? Call it caution. Lots of games are a blast for the first few hours and then fall off a cliff. Maybe this game's wonky targeting system will become a crippling liability. Maybe the missions will become repetitive grinds. Maybe it'll even start to take itself seriously. I can recommend a rental without hesitation. Beyond that, I can't say for sure until my PS3 makes it back home. When it does, this is the first game I'll be playing.
