In Call of Duty: Black Ops 6 Zombies mode, finding and activating the Pack-a-Punch machine on the new "Terminus" map requires completing several steps. Players start by turning on three AMP Generators across the map, defending each from zombies to power the area. Once powered, players can dive underwater to activate an inclined lift, surfacing the Pack-a-Punch machine for weapon upgrades. The machine’s location changes every few rounds, with increasing costs for each upgrade tier.
