Step 1: Rub your head whenever you can. If you have a hat on you can just remove it or tip it slightly for the same effect.

Step 2: When engaging in conversation always ask the NPC if you can "ask them something" or offer if you can "tell them something" - THIS STEP IS VITAL

Step 3: Constantly think about getting to Fort Benning.

Step 4: Bang Ricks wife.

Step 5: Enjoy! Playing as Shane is a great way to experience the game!
