To unlock Pack-A-Punch, you must first activate the power switch.

There are 3 switches located around the map that you must purchase for 1500 points each.

Locations:

-One in the starting area near the Amish Ale perk

-One in the garage area next to Double Tap

-One in the office at the back of the map near the Napalm Nectar perk


Once all 3 switches are activated, a door will open located in the hallway outside of spawn.
