3 Team Deathmatch

The idea of this is there are three teams in a map that is somewhat a triangle. Each team starts with X amount of points (maybe 100) and every time a team gets a kill on another, the killers team gets X amount of points and the dying team loses same X amount of points. Around the front there is some sort of objective to capture (maybe like Twisted Treeline) that when an opposing team captures it over time they gain points and the teams whos objective that is loses the same amount. the last team standing wins.
