Description: Buy all the items at the supply shack
How to obtain:
The supply shack is in the Soviet Installation. You can go there at any moment and you pay with the ancient coins. In most cases, you find the coins in various locations, but mainly in ruins that you explore, or in Challenge Tombs. You can find even more of them in special coin chests - their whereabouts are marked on the map after you read a monolith. Finding all of the chests should provide you with enough coins. If you are short by several coins, it is a good idea to explore the tombs that you have already explored, where the chances of finding the rest of the coins is the greatest.
