Note: The entire process takes place while the player is under the palace with the following glitch. Travel to Escalera. There is a palace at the top surrounded by cement walls. Enter through the doors. Note: Only one set of the doors work. Enter the palace and turn left. You will see a potted plant in a corner next to a bookcase. Get behind the plant by either jumping over it or walking behind it. Face the bookshelf and crouch. You should fall through the floor; if not, spin in circles while crouched until it happens. If you end up in some random room with no doors or windows, you will be stuck and must kill yourself to be freed. Once under the palace, you can shoot through the walls but no one can shoot back. To leave the glitch, simply walk out of any of the "walls." Attain a bounty of $1,000. Maintain the public enemy pursuit for ten minutes of real time. Make sure the Mexican army stays on you for that period of time. Wait for the pursuit to dissipate. Let the pursuit die out to unlock the achievement.
