South Park: The Stick of Truth - Shutout Achievement

Achievement - Shutout
Successfully block every enemy attack in a single, non-tutorial battle.

After you learn how to block in the tutorial, you can now get this achievement at any time. You must be attacked a minimum of one time by the enemy for this to count, so if you can fight as few enemies as possible, do as much damage as possible on your first turn while leaving one alive. Let him attack and make sure when you block it, you see a Perfect below your PP. Finish off the last enemy and you'll get the achievement after the battle is complete.
