I think 343 should re-add the flood in the campaign but make it a lot more gruesome.like in halo 3 how there were different classes and u had to destroy the corpses as to not allow them to revive.343 should make there be some faulty prometheans that can get infected with warped versions of there weapons. Andrew del rio should get infected but have a really slow infection where half the time he is still in control of his body but a gravemind starts to form. As master chief is battling andrew del gravemind chiefs long lost ally and friend the arbiter helps with defeating the gravemind. also, for the coop missions i didn't like it how there were 2 chiefs and it could only be a 2 person split screen. that's all i can come up with. i hope 343 can expand on some of my ideas.
