Difficulty: Moderately Easy
Step1
Start a game of bowling at one of the ally' s in the game. You will need 3 strikes in a row to get this achievement. This is for the xbox 360 version of the game.
Step2
Hold the left stick until your character moves 2 steps to the left. Then press A.
Step3
Concentrate on pulling the right knob back and pushing it forward as straight as possible. You can do it slowly but it will not give you the strike unless you do it almost perfectly straight back and forward. Do this as much as it takes to get those strikes in a row.
