Atomic Heart's abandoned Soviet-era setting echoes Stalker. Its incongruous architecture, reclaimed by nature, and hostile automatons reflect Nier: Automata. And its ensemble of gibbering nasties, first-person perspective, and, of course, penchant for battering baddies with blunt objects reminds me of BioShock.
Which is to say: Atomic Heart looks promising. Developed by Moscow outfit Mundfish, it's due at some point this year. Feast your eyes on an action-packed trailer:
Atomic Heart describes itself as an adventure first-person shooter, set in an alternative universe "during the high noon of the Soviet Union". Players fill the shoes of a special agent sent to a top secret facility—Facility 3826—by the Soviet government, after contact with the area was lost.
Within, players are met with a robot revolt, the dev explains on its official site, as they strive to restore peace and order. Moreover, Mundfish makes mention of "mind-boggling" abominations, experiments and the dead rising—which may be what's driving those gazeless gigglers in the trailer above. I'm terrified already.
