Pack-a-punch all three weapons then you will unlock the trophy. Don't forget to retake your weapon! Because of that I recommend getting at least one good gun such as the Ray gun to help you survive until the teleport re-opens, instead of just picking any random three guns. Every time you use the teleport a cage rises up around it so you will not be able to use it for a while. Even if you do have 15000 points I recommend taking three different runs into no-mans land as the zombies will just swarm you if your there for too long. You could either do it at the same time by saving up 15000 points or you could save up 5000 points 3 times as you play through the game. After getting any three guns you will now need to pack-a-punch all of them. Once you have bought that perk it will now allow you to hold three guns.

To get this trophy firstly you will need to make your way to the area where the Mule kick perk is. In Moon, acquire 3 Pack-A-Punched weapons at the same time. The final trophy, Cryogenic Slumber Party, is probably a trophy you want to save till the end of the trophy hunting as it takes a long time and you need to have a good knowledge of where certain things are in the map. It is not particularly hard, you just need two people to be able to do it, split screen and online co-op works. You could do the Ground control trophy in a match while getting other trophies or you could dedicate one match just to getting the trophy. The Perks in spaaaace and the Fully armed and operational trophies will probably take you two different games to get as they both require you to save up a lot of points and buy a lot of things.

You may as well go ahead and get the easiest trophy in the Map pack first, The One small Hack for man trophy. You will want to play the map first and get a feel of where everything is before you go for trophies as it is quite a big map.
