There a lot of people out there who would easily pick cod over halo or the other way around. I personally like them both, but I just wanted to hear what everyone else thinks. So which onces better, cod or halo?

Hey has anyone really saved the survivors stuck in the vault yet? Im having trouble with it because i just got the maps and everyone i get set up with to play is horrible. If anyone knows how to do it you should let me know.
