Okay for the people who want some custom games for with their friends, Me and my friend made V2 Gladiators(game type) on Gv2 Stadium(map variant). You spawn in the weapons room, choose yours, grab an ability and wait for the teleporter. when you enter the area u dish it out with your friends with one life. don't worry you have 300% damage resistance but no recharge for epic but eventually ending fights. http://www.bungie.net/Stats/Reach/FileShare.aspx?player=Royalflush55rr this is the link to my file share, My gamertag: Royalflush55rr and you can scroll through the maps and game types i have.
One night on(game type) goes with Orbital Station552(map variant) basically the humans were infiltrated by a lot of small covenant claw ships(my own thing) and the aliens shut off the power, you must survive the waves of aliens, watch out for their cloaking devices. good with 5+ players.
Next is Banshees(game type) on Aerial Stage(map variant) simply a fun dogfight over the waters near the hanger. 2-8 players.
For some more fun you can try D-day invasion(game type) on D-Day(map variant) This is a capture the flag where the American Spartans have to get a flag up the beach to the top of a hill while the spartan Nazis fire upon them.
Last, the is Ninja Training(game type) on Waterfall(map variant) balance is definitely clear for this one. Don't get frustrated if you fall because no - points for falling death and fast respawns.
