In this video guide I will show you how to get 25 brutalities. 100 brutalities, and 10,000 pints of blood spilled. Load up klassic towers, pick the first tower, pick anyone you want, and put it on very easy. Once the game loads up pause the game and look at the finishing moves page so you know what to do when the time comes.
To perform any easy brutality you will need to not block during the second round, hold the Y button, and press down on the d-pad + the Y button. You will only need to get their health bar down far enough that the uppercut will kill them and just make sure you have the requirements. The brutality should take their head off along with the spine for to to be a brutality. The achievement will pop once the brutality is done.
The pints of blood should follow shortly aster if you keep farming for the brutalities. Should only be several matches after the brutality achievement pops. Achievement will pop once the match ends.
