I didn’t know this was a thing – You have two teams of five from different countries fight MMA style in a huge ring.
Here are the rules:
We are using rules as close to real life as possible but in the meantime safety of the participants is our main priority. Our rules forbid blows to the Adam’s apple, groin kicks, biting and spitting. The team of five professional judges referees each fight. There are five fighters in each team in each fight. The rule of each fight is “the last man standing”; participants can give up by themselves or by the referee decision.
Here are two fights. I set up each video to start at the beginning of the match since the actual start of the video just shows a bunch of promotion stuff like girls dancing.
USA vs Russia
UK vs Latvia
