Perfection

Perfection is a medal awarded in Halo 3 Multiplayer for winning a slayer game with 15 kills or more without dying or betraying a teammate. It is represented by a black hexagon outlined in blue, which has another small blue hexagon in the middle. This medal isn't very difficult to get. This can probably be the easiest to be obtain in Team Slayer or Social Slayer matches. The trick is to camp and stay away from the enemies. When they advance stay out of sight then execute an ambush or assassinate.
