- Bring health back (Like CE or ODST)
- Make it harder (What happened to legendary making you try one part 50 times?)
- Bring Cortana back (**** man, you had to take the one thing he cared about away from him?)
- End the story (I don't care if the game is long, in fact I want that, but I want Master Chiefs story to end, and well)
- 4 Player Co-op (Don't make it all spartans, make it marines and ODST and maybe the arbiter, give them all different health and attributes that are unique)
