Rounds to win: 2 (or more)
Now do "Single Player" then "Single Fight" unless you want to do with 2 controllers. Select
Kotal Kahn as your character, and any CPU with
Very Easy AI.
Now allow the CPU (or other controller) to knock you down to
less than 10% health, and preform the
Blood Offering special move which is
(Facing Right). This move will make your character cut himself, inflicting 10.5% damage, which must kill you causing you to lose the round.
Now just go on to win the remaining rounds in order to get the overall victory using Kotal Kahn in order to unlock the achievement.
