This cheat will only work if done on insane!

1. You need to be on Level 4 Act 1 on insane difficulty.

2. Go through the level up until the building part and all through this time make sure you do not touch any ash bodies (this will also get you a secret achievement!).

3. When you get to the Hideout enter the secret weapons stash by entering the blue door on the right. In there you willl see a chicken with a pirate hat.

4. Hold X next to the chicken then continue on through the level.

5. During Act 4 Chapter 2 you will find two ammo boxes near a the cliff. Kick them off.

6. During Act 4 Chapter 3 you will see a third ammo box near a cliff on a podium. Hold X against the podium to cause it to fall down the cliff.

7. The Pirate Chicken will then arrive with a Cluckshot for each member of your party!
