Black Ops 4 Zombies: Blood Of The Dead – How To Pack-A-Punch | Upgrade Guide

To enhance your weapons in “Blood of the Dead”, the remake of “Mob of the Dead” in Call of Duty: Black Ops 4, you’ll need to construct the Shield and use it to your advantage. The Pack-a-Punch is back in a big way, making an appearance in all four massive Zombies maps. This particular map has an old-school flavor, with power switches and devices to build. You’ll still want to get that Pack-a-Punch as early as possible.

And doing it is pretty easy — if you know how to build the shield. The shield is, obviously, the trickiest part of this little Easter egg, and there are six possible locations you’ll need to check out to get the pieces you need. The last piece, the Warden Key, is thankfully always easy to get. You just need to defeat the Zombie mini-boss that spawns after activating both power switches. Get the full guide below for all the gory details.

Blood Of The Dead – How To Pack-A-Punch | Upgrade Guide

The Pack-a-Punch is a machine that upgrades weapons. You’ll need to complete Easter egg quest steps to unlock the PaP machine. Once it is unlocked, you can upgrade a weapon for 5000 points. The weapon will become stronger, have more ammo, get a shiny camo skin, and sometimes gain unique special effects, like explosive bullets.


Step #1: Build The Shield

To unlock the Pack-a-Punch in “Blood of the Dead”, you’ll first need to build the shield. To do that, you’ll need to collect three parts. Each part will spawn in one of three locations, so check all the locations listed below.

  • Part #1: Shield
    • Location #1: Citadel Tunnels – To the right (or left) of the door in the spiral stairs leading to China Alley. About halfway up / down the stairs.
    • Location #2: China Alley – Next to a zombie spawn window. The window is a metal fence covering a stairwell leading down into the Citadel Tunnels.
    • Location #3: Citadel Tunnels – At the top of the winding stairs, next to the locked elevator cage.
  • Part #2: Afterlife Essence
    • Location #1: Library – Look for an afterlife box in the original “Mob of the Dead” spawn room. The box will give a strange glow if the essence can be collected.
    • Location #2: Times Square – On the wall, on the first floor.
    • Location #3: Michigan Avenue – Directly under the “Michigan” sign.
  • Part #3: Warden Key
    • Drops from the Brutus Boss Zombie after activating both Power switches.
    • Power Switches are located in the Power House and Building 64 in China Alley.

Now, simply build the shield on a workbench!

Step #2: Drain Zombie Essence & Power The Shield

With the shield built, equip it and use the secondary attack to shoot lightning from the Warden Key, which drains Zombie Essence and kills the target. It takes a little bit of time to kill, so keep moving!

Drain the essence from five zombies (or more) with the key until it begins to glow with a bright blue aura. This powers-up the shield, and lets you transfer a charge to power things around the map.

Step #3: Charge the Pack-a-Punch Machine

The Pack-a-Punch machine is located on the Roof of the prison. Travel up there with the shield, and notice the power gauge to the right of the disabled PaP machine.

  • How To Power Up The PaP Machine:
    1. Charge the Soul Key by absorbing zombie essence with the Shield’s secondary attack until the key glows blue.
    2. Hold [Left Trigger] to aim with the shield, then press [Right Trigger] to launch a Soul Blast with the charged key.
      • The Soul Blast will charge disabled power gauges around the map.
    3. Use Soul Blast on the disabled power gauge to the right of the PaP Machine to activate it.

And that’s it! The Pack-a-Punch will charge up, allowing you to drop weapons into the machine for 5,000 points.

  • NOTE: The Pack-a-Punch moves every few rounds. After unlocking the Pack-a-Punch, it will teleport to a new location after several rounds pass. The Pack-a-Punch can appear in:
    • Pap #1: Roof
    • Pap #2: Building 64 (East Side Power Switch)
    • Pap #3: Power House (West Side Power Switch)
