When one team loses its first guy it's basically game over. The guy that is freed up can join a friend and its two on one, then three on one, then four on one, etc.
The last guy on the losing team is basically put through a meat grinder.
At first I thought it might be good entertainment, but it turned out to be just a bloody mess.
I’ve seen is team MMA where 6 or 8 guys on one side go at 6 or 8 guys on the other.
