While I think there are many superior single-player FPS games to Atomic Heart, very few manage to surprise you and bombard you with surrealism quite like Mundfish's shooter. Sure, its suggestive robots helped catch a lot of folks' attention, but it's become a successful hit on its own merit too, thanks to its wacky premise and alt-history Soviet aesthetics. So successful, in fact, Mundfish has got a sequel and an MMO-shooter spinoff called The Cube on the way. However, before they arrive, the last pages of Atomic Heart's story need to be turned, and its fourth and final DLC will do just that in April.
