So i was wondering in the co-op campaign, who would the second player be? In halo 3 it was arbiter. And i know that AI have a bigger role in this game. What would you like to see in the game? I want to see some new things (unlike a series we have all hear about that has been 8 times in a row not changed much). I would also like to see dual weilding come back,new weapons, new maps, new gametypes and definitely stronger human vehicles. What do you expect?
