what about destructable evironments, i always wanted to see master chief bust throught a wall or tear a ghost in half or something. i think they should add ur exellent ideas as well as some more personalized ones to give halo 4 those little details that make it amazing. and as far as scarabs go and driving them, i can understand why they dont let you do that in multiplayer but why wouldnt someone want to hop in one and lay waste to the covenant in campaign?
