Well, the basic idea is that a group of rabbits enters some kind of arena, which is going to be flooded with enemies. Above the arena there's a tower with enemies, and each time the host destroys a crate, a bunch of enemies fall down which will respawn after ten seconds. So after each crate, extra enemies come into the game. The rabbit who stays alive for the longest time, wins the game. I also included a spectator mode.

The system works about the same as Ground Force, and it has the same startup system. However, the host can't join in the game and once someone's dead, he ends up in the beginning of the level again. Like someone who joins a Ground Force game which is already busy. Anyway, to make the system in a way that rabbits can't kill each other and only the enemies, the only way of hosting this is in Co-op. I shall try to release a level with this new game-mode (I call it "Bring Em On!") in the near future.
