Other ways to get the Ray Gun Mark II
If luck or Gobble Gums are on your side, you might not need to take all the steps above to unlock the gun in the Armory. The Ray Gun Mark II Wonder Weapon can be gained by getting lucky with the Mystery Box, or if you use the Wonderbar Gobble Gum, you will be guaranteed a Wonder Weapon on your next Mystery Box spin. However, the gum doesn’t specifically guarantee you the Ray Gun Mark II.
However, it’s worth noting you only get one Ray Gun Mark II Wonder Weapon from the locked stash. So, if you want your teammates to have one, you’ll need to try and get lucky with these other methods.
