here's my idea. you have a BR and a magnum(or magnum if BR isn't in reach.). grunt birthday party is on. you're in a map with nothing on it. there are tons of grunts running away from you. there is individual scoring. Your objective, to get the most points in 10 minutes (maybe less/more time.) You can play with up to 15 other people (maybe less).
Or, two teams trying to get the most points.
thoughts?
EDIT: Another idea, maybe a hunt gametype like in starwars battlefront 2. You can play as either a Spartan, Brute, Hunter, Grunt etc. and basically fight. the species that gets the most points by the end of the time limit wins.
