This can be done in a solo game and completed once the second area is opened. Weapons only found withing lockers suck as the LSAT are not required.

The weapons you must use and areas they can be purchased are as follows: There are two weapons of each type (Assault Rifle, SMG, LMG, Sniper, Shotgun) plus the Hybrid Weapons from previous DLCs in Awakening. It doesn't mention it in the achievement description, but after much dismay and several methods and list keeping, we discovered that you must do this entirely in a single match. They are randomly in the side areas guarded by mammoths, and there will only ever be four on the map at any given time, so don't get greedy. The ARK attachment is new to Awakening, and once equipped will transfer to any other weapon you replace that weapon with, so you only need one, regardless of the Transfer Attachments armory perk.
