I remember in the first Crysis there was an option for blood on/off, it would be sweet if they could add an option for the helmets on or off. This is one of those things I doubt would happen but damn it would be cool. Or maybe we could knock the helmet off their head...First you choke them with one hand, rip the helmet off with the other and then punch them in the face before you chuck them away.
What are some other ideas you may have thought of that would be cool?
