How to Get Pack-a-Punch in the New Zombies Map

Select the Moon map from the Zombies menu of ̶0;Call of Duty: Black Ops̶1; and begin playing it as you normally would. Open doors and continue to enter the new areas as you get to them. As soon as you reach the power switch, walk up to it and press the button indicated onscreen to turn it on.

Walk into the outside area when you get to it. You'll see a perk machine in the corner up ahead and another building to the right of the perk machine. If you don̵7;t see this, you aren̵7;t in the right area. Continue working your way through the map until you find it. Once you find it, walk toward the building near the perk machine. As you get closer to it, you see a platform with a vortex in the middle.

Jump into the vortex. You will now be teleported back to the spawn point on the map, right next to the Pack-a-Punch machine. Walk up to it and press the button indicated onscreen to activate it. It will now take your weapon and pop out an upgraded weapon. Once the weapon pops out, pick it up and jump back on the teleporter before you get overrun by zombies.
