no oddense but think about it, what was thw worst level in halo 3? cortana is what most would say, and it is considering you are dealing with the flood, alone and in the end is when the arbiter finaly saves the day, personaly i just hate the flood and , guys to tell you the truth, they said that the flood will not be in halo 4 but vehicle info i don't know but check on waypoint if you want, but they have released weapons and amrmor ablilities in halo 4 so just go to youtube and check out halo 4 and look at the tournament they had and see it all( no vehicles) in action, and my fvorite gun so far from what i see,BR or DMR. They both look amazing.
