Here is a guide on how to get the final 3 Loadouts in case you’re stuck on 139/141.
The Loadouts and How to get them
You might already be guessing how you get these, just from the statues these guys look pretty familiar.
Basically the way to get this is you have to complete the Master, Blacksmith and Shop Achievements and then once you return to base you’ll have the loadouts unlocked and ready to use.
(I haven’t done the merchant one but you get the basic idea)
After you complete these and claim them while on a run, the sets will be unlocked once your run ends.
IMPORTANT: If you’ve done the achievement and the loadout isn’t unlocked start a run and leave it and you’ll “refresh” your home area and the loadout should be unlocked.
