Like most maps in BO6 Zombies, you get a chance to unlock the Pack-A-Punch upgrade to help improve your weapons or stats. Unlocking and activating the Pack-A-Punch for the Reckoning map is a tedious task, as it involves several steps to unlock it. To know how to activate the Reckoning Pack-A-Punch, keep reading about it below.
Locating the Pack-A-Punch in BO6 Zombies Reckoning

The Pack-A-Punch spawns after you restore the Particle Accelerator by shooting 12 Aether Crystals. However, to reach this Particle Accelerator, you first need to start from the spawn point in the T1 Project Janus Reception. Then, take any of the elevators on either side and head up to the Mutant Research Lab. From the Mutant Research Lab, take the portal to the T2 Android Assembly.
You will find a locked door, unlock it using Essence, enter it, then take the elevator up to T2 Dark Entity Containment. Use the portal launcher here to get to T1 Executive Suite. Head up to the upper floors to T1 Director’s Office, and use an explosive to blow up the door.
Head inside, then press the button on the table to bring up a portal. This will take you to T2 Sublevel 10, walk up the stairs on the right and enter the doorway to the left of the Vulture Aid Perk-A-Cola. Interact with the console to activate the Particle Accelerator.
Activating the Pack-A-Punch

The Particle Accelerator will quickly become defunct, and you need to find a way to restore it. Look around the area to find yellow markers, which are locations where you will spot a handful of Aether crystals. Use your weapon to shoot them all down to restore the Particle Accelerator. The Pack-A-Punch will also spawn in the lower section, utilize the zero gravity within the room to access it, and upgrade your weapon.
