Atomic Heart is a mixed bag, the game clearly had interesting vision but fell apart at some point.
The game has great art direction that makes you stop and admire the visuals, it has good music that ranges from classic bits to techno and house music, it has fun gameplay when you start to upgrade and acquire abilities, it has fun bosses to battle and it runs crisspy smooth.
But it also has very poor writing which wouldn't be a problem if the game didnt constantly shower you with it, the characters are all unlikable and lack any interesting personality, the low enemy variety starts to become bothersome late into the game and the gunplay doesnt feel satisfying enough.
The open world is tedious and has nothing worthy to explore, the best part of the game is when you are inside polygons because the characters shut up and the puzzles are interesting to solve, plus you get good rewards, thats where the game peak.
The game can also get buggy which wouldnt be a problem to me if it had depth to its interactivity to counter that but sadly it doesnt.
For a first time attempt the developers got many things right but they also have a lot more to learn and improve upon.

Its alright i guess, i dont feel robbed after finishing it so i guess its not bad.
