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.
How to Find the Pack-a-Punch Machine in The Tomb

Unlike maps like Terminus and Citadelle des Morts, 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.
To access the Doorway to Nowhere, navigate to the Subterranean Temple area (easily reached by progressing through the map). Inside the Temple, locate the altar and place the Amulet (you'll start each match with it). After a short wait, the Doorway will open, granting access to the Dark Aether Nexus.
Initially, the Pack-a-Punch machine resides within the Dark Aether Nexus, near the center. However, its location changes over time.
All Pack-a-Punch Locations and How to Find Them

The Pack-a-Punch machine can spawn in two locations on The Tomb. Its first location is always the Dark Aether Nexus. The second is the Roman Mausoleum, an ornate ruin at the top of the Dig Site.
To determine the machine's current location, consult your Tac-Map. The Tomb's main area and the Dark Aether Nexus have separate maps. If the Pack-a-Punch icon isn't on one map, it's on the other.
Alternatively, check the stone slab displaying illuminated areas. If the Pack-a-Punch symbol is on the main map, head to the indicated location. If it's shown on a separate island, it's currently in the Dark Aether Nexus.
