a game suggestion: a very cool gamemode thingy
ok, so you run through the game and rip through grunts, leaving bodies everywhere. empty guns and crap, but after you complete the level, you get the chance to go through it again as a janitor, picking up empty guns and cleaning up (which is already a mechanic) and picking up bodies, like viscera cleanup. example:
just a idea. but i think it would a very good mechanic.
