Well I've been hearing all sorts of rumors about the game being more team-based, and you're supposed to be playing with a group of spartans. I think it would be cool if they tried something similar to the PS3 game MAG, where you have big battles, say 25v25 or 50v50, and the teams are split up into squads of 5 spartans. Each squad will have different objectives on this huge map, and these objectives will lead you to proxy battles with other squads from the other team, occasionally spilling over into a huge chaotic battle somewhere in an arena area on the map. I think that would be really cool.
