Atomic Heart

The Makarov Pistol is abbreviated to "MP" in game for whatever reason. So ensure it's the MP gun your using to do the aimed headshots.

I found the best mobs to headshot were the white Vova engineers. Either freeze or electrocute them so they stand still - then with the Makarov Pistol aim down sight with and put a few round into their heads to kill them.

Due to Atomic Heart having achievement tracking reset issues it's best to do all 25 in one sitting. The best way to do this is find a save point within a few yards of a Vova engineer. Save, then kill him with aimed headshots. Reload and kill him again. Rinse and repeat 25 times to unlock the achievement.

EDIT: Unsure if you can still get this via reloading a checkpoint, so check the progress on the achievement if you attempt to do so. That said the latest patch says they fixed the single session issue, so you may be able to get this legit over multiple game sessions now.

Apparently this is glitched and you need to get 25 aimed headshots in a single sitting.

Luckily it's possible to get this by exploiting the checkpoint system.

Simply find a Vova near a checkpoint, Freeze/electrify them (may as well work on the Avatar achievement while doing this) Aim at their head and kill them.

Then just load your previous save and repeat.

I did this in the room with the locked door to the seed bank (you collect 3 moon samples or something for a lock)

Ok so this is one of the many bugged achievements. At the time of writing this (April 20, 2023), tracking works but it is still bugged.

I tried all of the other guides using Vovas to get headshot kills, but not all headshot kills were counting. In fact, very few counted. What I found to work were Spores. Killing Spores while zoomed in with the pistol counted almost every kill. I guess Spores are the heads of Mutants, so by themselves they are all head, making a headshot kill the only way to kill them. That's the only logic I can make of it but I still was aiming at the center point, not the petals. I did this after completing VDNH, in the open world map near Testing Ground 9. There are a bunch of Mothers spawning Spores there. The Mutants and the Spores both counted towards this achievement.

The best part is Spores continually spawn if you don't kill their Mother. Once I saw those kills tracking, I probably spent no more than one minute killing about 20 Spores (I had about 5 already tracked).

I hope this helps everyone else experiencing the same problems I was.

Tip: for the achievement to count, always hold the pistol while aiming after getting a headshot. If you stop holding LT right after getting a headshot, it won't count.

Pretty simple achievement, mostly aim for the simple Vova enemies, since they have the least amount of health.

You can turn on Aim Assist if needed.
