This is merely a post to get everyone involved and show the communitys creativity.
Is this the right forum for this? Not sure… Ah well, I’ll bite.
Fiesta FFA
Team Rockets/RocketsFFA (Nothing but rocket launchers with infinite ammo and regenerating frag grenades. No equipment)
A KotH/race/territories hybrid where you are in a warthog, ghost, or mongoose and have to push everyone else off the hill - a floating platform in the sky. Last one in the hill wins the round.
Let’s have Hockey from Reach Action Sack return, and Dinoblasters too!
Mostly Action Sack ideas ^^;
Creative Game-Types:
-Hacky Sack (Throw the odd ball from person to person without falter, or the thrower dies.)
-High Stakes (Regular Race with warthogs, but the twist is on start and respawn you are outfitted with random vehicle abilities to obliterate or humiliate your opponents. E.G. spike-strip, mines, smoke.)

Good ol’ Monster Trucks <3
Despite being a competitive minded player I loved the thrill in this game mode 
Defender (Generator defense)
2 rounds. One team defends a generator or object, the other team has to destroy it within the time limit. swap teams for second round. Fastest team wins.If the generator isnt destroyed, the defenders win the round. if neither team succeeds in destroying it, winner is decided by damage caused to generator.
Execution
Multiple rounds. Each player has one life. All players are given the same random weapon which changes each round. Rounds are won by wiping out the enemy team. Team that wins the most rounds wins the match.
Hunter
FFA. Each player is assigned another player to kill. The only way to earn points is killing the assigned player. You do decreased damage to non-assigned players. Killing your assigned target gets you assigned a new one. The longer you live and more score you get in a life, the more players are assigned to kill you.
Just a few I think would be interesting to see.
Invasion but with Spartans vs Flood.
Multiples weapons classes for Spartans against multiple forms and weapons for Floods, and played on floodyfied maps.
My suggestion is quite simple: Capture the Grunt
