Who would win in a fight, doom guy has his plasma repeater and super shotgun and master chief has his assault rifle and shotgun. Both have frags and they are in a gladiatorial arena with plenty of cover, and plenty of open space as well. Please put away all nostalgia for both fighters and just give your honest gut feeling. I understand that screw attack has already done it, however that video is out of date seeing as we learned a whole lot more about doom guy from the new doom game.
