Team Fighting Championship is a 5-on-5 mixed martial arts league, and judging by the video above, it is one of the most insane sports in existence.
The teams from Poland and Sweden in the above video waste no time feeling out their opponents and begin the match in a blur of tackles and flying kicks. In the sport's most vicious twist, fighters are allowed to gang up on opponents so the end of the match is just a five-on-one beat down. You truly are only as strong as your weakest link.
TFC's website says that the league is based in Latvia, but this appears more like something that could only occur in international waters.
