In Moon, acquire 3 pack-a-punched weapons at the same time
Buy the mule kick perk which costs 4,000 points which allows you to have three weapons, ( the location of mule kick is in the video)
Use the teleport to travel back to no mans land and pack a punch one of your guns at a time throughout three seperate journeys as too many zombies arrive at once. Or you can take the hacking device with you and hack the pack a punch machine. Leaving a crawler doesn't affect the amount of zombies in no mans land.
After you have all three weapons pack a punched at the same time your achievement will unlock for 25g
I Pack a Punched the HK21, Ray Gun and the wave gun
