Here is my little review of Atomic Heart:
(The political situation, takes with me no influence on the evaluation of the play and I comment on it also not)

Pro:
- Very good graphics, even without RTX
- Excellent game-/gunplay, both with keyboard and controller
- Interesting story set in the blossoming UdssR
- Cool characters with recognition value
- First Bioshock-like in years, from an absolutely unknown studio
- Challenging enemies and bosses
- Enemies don't "respawn", they get fixed. In the process, you can watch.
- Beautifully designed sci-fi robots
- Never before has a vending machine been so friendly to me xo xo
- Grinding is possible and can help when you are stuck

Con:
- Open world rather unnecessary than worth exploring
- Collectibles and upgrades are scattered all over the world, which is not very accessible
- No quick travel points
- You can't use waymarkers.
- Always a huge pile of enemies in front of some paths.

Conclusion:
In my opinion a very good shooter that Mundfish has delivered, it can join the Bioshock games 1 to 1, no matter if it's design or music everything goes in the same gloomy/dystopian direction.
For me an absolute feast.
It's challenging but not overwhelming, at times you feel more on the run than fighting, once the enemies have sounded the alarm you have to take your feet in your hands. Which was always fun for me.
As for the story, I can only say (without spoiling) that it's about the Soviet Union planning the next "big" leap with the help of new technology, and then everything turns out differently than you would expect. From my side a clear recommendation for this game, for every Bioshock fan a must!
