In this video guide I will show you how to perform two different fatalities with Frost. For the first 10 characters I just used the klassic towers to get the achievement progress for I Want It All. Make sure to put it on very easy to make things quicker. Also pick the shortest tower.
After getting your I Want It All achievement the method with be a lot faster. Once in the main menus press the start button to go into the options menu. Scroll down to change the rounds to win to one. Then back out, go into the fight menu, select local, make sure to press X to turn on the CPU, and then select your character. You only have the one health bar to deal with to get to the fatality.
Achievement progress also counts if AI do a fatality.

Ice Sculpture (Close) - Forward, Back, Down, X
The Cyber Initiative (Mid) - Back, Forward, Down, Forward, B

Another way to get this achievement is to go to AI Battles and let the computer fight. Simply pick 3 fighters you need the achievement for and then start the match. Enable FAST FORWARD X4 to speed things up. Once a fighter's achievement unlocks, change that character to another fighter u need the achievement for. This also works towards the achievement for playing 10 and 25 AI Battles and the achievement for spilling blood.
