In halo 5 I think action sack and multi team would make a reappearence. There should be a longer campain and a new multiplayer race. The thruster pack should be improved or be changed into evade. Holograms should be more believable and walk around corners and walls and have a gamertag. The campain should explain the war. When you play multiplayer you should be in spartan armor and walk into the type of game mode you want to play or custom games. There should be a large forge map with different landforms and small amounts of water, like forge world in reach but better.
