Anything, just pick anything. Or if you wanted to remove something, what would you remove? Whether it be bloom, armor lock, or certain guns.
Mine would be to add Valhalla and Sandtrap to Matchmaking, so many good times on those maps… Reminiscing Look
Real Bloodgulch.
Multiplayer bot matches.
Flocks of Picachu on every map.
All spartans replaced with Justin Beiber’s in matchmaking.
Replace all game music with ‘It’s raining men’.
Kill the last 3 quotes. And space fighting in Seraphs and Sabres.
I would have to say I would like to add to Reach something like an option to be dropped into the match for respawn or not. Think how section 8’s spawn system worked and you’ll know what I mean.
Or just be able to choose your spawn so you don’t come back into the game only to be killed a few moments later.
Some free maps, I feel entitled to some because some of the on-disc ones aren’t so hot.
Working elevators, Firefight for Forge world, Target locator weapon in forge.
Flood Firefight. Not like that terrible gametype that is regular Firefight, though. Make it more like CoD zombies - it has atmosphere, and you unlock new areas of the map as you progress and find new, more powerful weapons. Give it 3 or 4 huge maps that would take hours to explore fully, and have properly integrated vehicles. It would be beyond awesome.
same here i would love that to happen. CoD RULZ!!!
Kill Cam!
I think it would be drop in/drop out Firefight.
“Oh look, Bob’s on Firefight, I’ll join him”
“Hi Steve! Glad I didn’t have to quit out to the lobby for you to play with me”
Oh, and for Infection, it would either be Covies as the infected or the Flood
a covanant mission or a whole campagin being the grunts version of noble team
I’d definitely add a Grifball playlist…

Well of course you would.
You kicked my inexperienced butt all over the Grifball court that one day.

That’s exactly why we need the playlist - so you can find someone even more inexperienced and kick their butt!

Probably.
GRIFBALL!!!
I want Grifball so bad! I don’t know what the official term is for launching a ball carrier at the very start of the game to get a goal, but I coined the term “Flying Melon Drop”, and I’m still very fond of it.
