How to Pack a Punch in the Call of Duty Black Ops 2 Zombies map Origins.
In order to Pack a Punch you will need to power 6 generators spread throughout Origins. In order to activate each generator you will need to Pay 200 points solo or 800 points multi player at the centre control panel for each individual generator.

The 6 locations include:
1. In the room just off the Spawning room.
2. Just outside the tank station near the workshop.
3. To the left off 1 of the trenches to No Man's Land.
4. Directly beside the Juggernog perk machine in No Man's Land.
5. Near the Stamin Up perk in a broken building.
6. After you head through the broken church.

Once all 6 are activated you can now pack a punch at the excavation site in the centre of No Man's Land but be warned that each time you activate a generator Crusader zombies will spawn top protect the Generators. Also Crusader zombies will randomly spawn and begin to destroy activated Generators.
