in halo 5 i want the enemy to be the precursors or forunners or both which are two really powerful enemies and have these enemies threaten the humans and covenant and so they would have to team up to stop them and for the campaign have master chief and the arbiter in it with seperate missions like halo 2 and at the end be in the same missions. for forge i want a world like skyrim but not as big with multiple enviornments with open areas and put everything in forge. for weapons just bring every weapon back maybe not put them all in multiplayer but have them for forge and campaign and etc. I want various new vehicles for every race and i want old ones to return and new weapons. i want firefight to come back have the classic firefight but also other gametypes for it and keep spartan ops.for multiplayer balance it out and be able to play as an elite. and add new gametypes that are tottaly differnt than were used to like space battles and large halo wars type battles and put the halo wars vehicles in the game.and add fun gametypes that were in halo 3 like action sack and rocket fight just fun gametypes and bring back halo 3 maps like sandtrap
