How to unlock the Ultimate Knockout achievement in UFC 2009 Undisputed - Definitive Guide
This is similar to the achievement above. Use the same strategy, thudding your opponent with punches until your both a mix of blood and sweat. Remember that as easy as it is for you to knock them down in this state, the same applies to the computer. So keep your fists up and the remaining stamina higher then theirs before you come in for the fatal blow. If your having trouble, hook up another controller or ask a bud to play with you online.
