So if you are missing a few weapons, such as the Hellbreath or Heavy Automatic Shotgun, you could always go to the chapter where it can be found/bought and then kill an enemy later or in its following chapter. This can be a tricky achievement to get as the weapons are not listed in-game and many of the weapons can only be obtained at certain locations.

In Metro 2033 this is not accumulative, which means you need to kill within a single chronological play-session of the game (i.e.: no chapter select, even after beating one). 3.1 Standard Method (Metro 2033 & Redux).
