When you kill your enemy, it'll respawn inside the arena until someone makes 2 points of difference. Score will be printed to everyone when someone in the arena gets fragged.
After all players or bots already played a round, the guy who is on the top of the scoreboard is the champion. See readme for more details.
You may need a recent version of darkplaces to run this mod.
