Pack A Punch helps you upgrade weapons, but unlocking it on Black Ops 2 Buried is as challenging as clearing out the zombies. Before solving the Pack-A-Punch mystery, ensure you have freed Leroy, earned 1,250 Points, and equipped a ray gun.
Next, go to the haunted mansion in the underground western town. Then, follow the steps in the guide below.
Enter the Mansion
To enter the haunted mansion, you must first have Leroy with you in Black Ops 2. Feed him booze or candies, and he will smash the mansion’s gates. Before you get here, make sure you have earned 1,250 points to open the mansion’s front door.
Avoid the Ghost Lady
Make your way upstairs, and you will encounter a female ghost flying towards you from the left stairs. Don’t let it get near; shoot it with a ray weapon.
Find the Maze Behind the Mansion
Enter the room on the left stairs, and a bookshelf will move, opening a hidden pathway. Always have the gun ready to shoot because the ghost reappears many times here.
Move to the end of the narrow pathway and exit it from an opening on your right, which takes you to another room.
Make your way out of the room and into the wooden flooring hallway and take a left turn to find a huge opening in the left wall. This opening will take you to the gardens where you will find the maze.
Solving the Maze
Take the first left before the fountain area. Keep going straight, and when you see two turns on your left and one on your right, take the far corner right, as shown in the image below.
Keep going straight, and when you get two turns again, take the left one. This will eventually lead you to a locked door, which is your clue to the correct path.
Turn back from this place and take the left turn. Follow the path straight path, and again, you will have two path choices. Take left again which will eventually take you out of the maze.
Getting to the Pack-A-Punch Machine
Climb down the stairs of the building that comes at the end of the maze. Watch out for the broken areas on the staircase, and you will end up near the Pack A Punch machine in the Buried map. Now, activating the machine will also activate the Hell on Earth. The place will begin swarming with zombies, and you will not be able to get out until you kill off of them.
