Metro 2033 Redux

This achievement may not come naturally over the course of either playthrough, but don't worry, it's not missable. All that is required is to make at least thirty "deals" at any of the weapon shops between the levels “Exhibition” and “Polis,” as after that there are no more vendors. Take note that purchasing ammunition or equipment (grenades, medkits, filters, or throwing knives) does not count for this achievement. You will have to buy weapons instead.

A great way to grind this out is to wait until you get to "Polis." By this time, you should have around 600+ military-grade rounds. Head over to the weapons vendor, buy the Bigun, and then sell it back. Continue to repeat this method until you've either run out of military-grade rounds or the achievement unlocks. If you do run out of currency, just reload the checkpoint and keep repeating the method since progress will save after every purchase/sell regardless!
