Be at any Planet Where your Ratchet walking. Note: You must have the decoy gun before doing this. Stand in front of the wall you want you want to go through. Take out your decoy gun and then lay on as close as you could get one on each side of you with out making it fall through the floor. You have to be facing away from the wall when doing this. If done correctly the screen should be shaking. Now lay a decoy directly in front of you which should also be between the other two. What you just did was have the decoys force you through the wall.
