In *Call of Duty* Zombies, the Pack-a-Punch machine is your ticket to significantly upgrading your weapons. However, finding it in *Black Ops 6*'s new map, The Tomb, requires a bit more legwork than in previous maps.

Unlike some previous maps, simply reaching the Pack-a-Punch machine's location isn't enough. First, you must open the "Doorway to Nowhere," a teleporter leading to the Dark Aether nexus within The Tomb. This is achieved by progressing through the map, reaching the Subterranean Temple, and interacting with the altar using the Amulet (which you'll automatically have at the start of the match).
Initially, the Pack-a-Punch machine resides within the Dark Aether nexus, near the center. However, its location changes over time.

The Pack-a-Punch machine has two possible locations in The Tomb. Its first appearance is always in the Dark Aether nexus. Its secondary location is the Roman Mausoleum, an ornate ruin at the top of the Dig Site.
To determine the Pack-a-Punch's current location, consult your Tac-Map. The main map and the Dark Aether nexus have separate Tac-Maps. If the Pack-a-Punch icon isn't on one map, it's on the other. Alternatively, check the illuminated stone slab; lit areas on the main map indicate its location there, while an island icon indicates its presence within the Dark Aether nexus.
