I remember hearing about this a while back. Didn't know it was already so solid. Shit is tight. I think they just fight a single 3 minute round so they have to go full blast the whole way. There's no time to feel out the other guy during the first round or anything like that and the referees penalize fighters for "passivity".
Action packed. Me likee.
