To perform a Babality, you need to win the last round without blocking. And, obviously, run the commands of the character you are using.

You need to follow the steps:
- Don't lose any Match (you can lose rounds normally)*
- Finish all foes with Babality, until Shang Tsung.
- Don't block against Goro/Kintaro and Shao Kahn cause the Babality rules.**
- And finally against bosses, if you do this correctly, the babality 'll be executed automatically.

You can see my video here.

*I don't know if you need to play on expert or it works in all difficulties **I think that isn't work if you don't attempt to the rules about babality[/i]
