In the beginning of the game when you are being awakened by Doctor Mitchell, when you test at the Vit-o-matic, move your intelligence to 10, or when you choosing skills, choose Repair. Note: You need at least 25 points in Repair. Go to the Sunset Sasparilla crate with the broken 9mm SMG and pick it up. Repair it while repeatedly tapping [Confirm/Activate]. You will be able to repair it again. The game will glitch and you will obtain 20 experience points as well as two 9mm SMGs.
