[Snow Man Of 904]

All you do is Team Leader on Kill House set the room to 10 people so you get no negative modifier. Alpha Kills/Bravo gets killed by Alpha. You run up the stairs go right down that ramp and alpha just kills bravo and you swap teams so you each take turns. Alpha all ways gets 400XP but if you kill someone it adds onto the 400XP and just keep launching over and over I got my Elite the 2nd day the game came out so its not hard. Another way is you do the first level of the campaign on Realistic so you get 10xp every kill once you get to where you disarm the bomb shoot your guy and throw a grenade at the guy disarming the bomb and once disarmed the turret up above will glitch the guys to spawn their and all you do is sit their an shoot them I was told you can do this all day and they keep spawning but I've only done it once so...Enjoy
