There are no rules!

The Ultimate Fighting Championship Volumes 21-30 starts with some significant rule changes. Preliminary bouts now consisted of two five minute-rounds, main card bouts were three five-minute rounds and championship bouts were five five-minute rounds. Return Of The Champions was the first UFC event to adopt the 10-point must system, commonly used in boxing, to judge fights instead of each judge merely stating their choice of fighter. Boxset Includes: Return Of The Champions, Only One Can Be Champion, Ultimate Japan 2, First Defense, Ultimate Japan 3, Ultimate Field Of Dreams, Ultimate Bad Boyz, High Stakes, Defense Of The Belts & The Battle On The Boardwalk.
