To unlock this achievement, you need to purchase all Primary weapons, Sidearm weapons and Explosive Items. In total, this will cost you
approximately 270,000 gold.Gold is obtained in many ways; collecting it from dead enemies, opening chests, locating relics and discovering it in the environment. Any gold you obtain is only saved once you’ve completed that level. In Horde, gold is saved after each wave.
As there is no easy way to farm gold, so you must replay the campaign or Horde many times over to accumulate enough gold to buy everything.
Note: Any weapons that are included in DLC packs do not count towards this achievement.Primary - 186,100 total
