Some tips: *You will win this trophy eventually. *I only performed babalities to win the trophy. By the way I unlocked everything in -The Krypt- before I tryed this. *No,I didnt perform every characters second fatality. *Some guys are reporting that they did all the babalities but the trophy/achievement didnt unlock for them. *if you want to perform all the babalities first,good luck.I recommend to unlock everything in -The Krypt- first.
FASTEST WAY (2 controllers): *Change Options to 1 round and 30 seconds. *Start -Versus Mode- 2 players. *Select your characters.
Use the next cheat: Sans Power (0,4,4) (4,4,0)

*Now,hit once,perform babality and select character again,repeat.You need to perform a babality with every character.Last one will give to you the trophy.
