I want to have split sections like Halo 2 and Halo 3: ODST where we play as different characters. I have no idea of Halo 5’s plot, but I would like to play as the Arbiter from time to time. I want Chief levels and Arbiter levels. Also, I want brutes back as enemies in some form and the Arbiter levels would give us a reason to fight them.
I also have been wondering how co-op should work. Do you think they should just clone the main characters or do something like Halo 3 where the other players are regular elites? I liked playing with unique elites in co-op, but I’m not sure who would fit that role for Chief’s missions.
