NexRouge - everyone starts as Blue. There is a Red-Flag-type-of-object hidden somewhere (obvious place though). Then, the first person to get it will be the Rouge. When you're the rouge, for each Kill you get 3 points, and once somebody kills you, the flag-type-thingy will be dropped at the spot of death, and the next person can get it. Yes you get A point for killing the Rouge.
EDIT: Also, i think when a person falls off the edge, the flag-type-of-object (lol, I never get sick of saying that) should reset... otherwise it's impossible to get
