This game is going to be AWESOME! There is a SIGNIFICANT difference between this game and most first-person shooters, and I will try to explain why. Nearly EVERYTHING in the areas is interactive. I watched an example on the net of people making it trying it out, and they set loose a beam that knocked over ALL their enemies. THAT is uber! You can use barrels and things like that. Anything around you can be used on enemies; to slow them down or kill them or whatever. I am not really great at explaining this. Maybe someone else can explain it even better?
