Which chief are we putting against him? The current experienced mc, or mc at his start (as the guardians are). I think if you put the guardians against the current chief they would beyond whooped. Like all mc would have to do is look at them to kill them, only because he is so much more experienced and his armor has been upgraded a few times. Now say we put the guardians against MC circa Halo: CE, the guardians stand a much better chance as they are fighting the chief as they are now, at the beginning. I've had the misfortune of never having played the masterful Halo: CE (I've seen a friend play it, or it might've been Halo 2 idk) so I can't get a good conclusion as to what would happen. Only reason I say he would whoop em is because I've played Halo 4. So for the sake of being fair to the guardians lets put Halo: CE MC instead of the current MC
