South Park: The Stick of Truth - Heisenberg Achievement

**This is a Missable Achievement **

The goatee is located in Cartman's bedroom. Loot it from a dresser. The bald cap is in the bag in Romper Stomper's cell in the police station.
Make sure to equip both. You need to wear them before you go to Kenny's house during main story quest to recruit Tweak.
This is one of the first quests in the game, so make sure you go to the Police Station right away. After you defeat the Meth Tweekers, the achievement will unlock.
