Atomic Heart is a first-person action shooter set in an alternate-history Soviet Union where advanced robotics and polymer technology have created a utopian society that goes horribly wrong. The Polymer Glove gives protagonist Agent P-3 elemental powers (electricity, ice, telekinesis) that combo with firearms and melee weapons for devastating synergies. Combat blends BioShock-style power/weapon combos with melee action inspired by souls-like timing. The open-world sections between story facilities hide optional dungeons called Testing Grounds filled with challenging puzzles and powerful loot.
Atomic Heart features distinct areas with increasing difficulty. This guide covers every major location in progression order — what to do, what to get, and when to move on. For the step-by-step path, see our walkthrough.

Exploration Tips
- Clear areas in order — Facility 3826 → VDNH Complex → Polygon Testing Grounds → Limbo → Chelomey. Skipping areas means missing resources you'll need later.
- Check every corner — Hidden caches and secrets are often in non-obvious locations.
- Match your weapons — Some areas favor different weapons types.
- Read the walkthrough — Our walkthrough provides exact progression milestones for each area.
- Don't rush — Clearing an area fully gives more resources than speedrunning two areas.
