This is add-on content, not a standalone release. You need Atomic Heart itself to play it, and it picks the story up rather than starting a new one.

Back into the facility

P-3 is pulled into the Mendeleev Complex and the swamps around it, chasing the truth about NORA. It is a new slice of the same dystopia, and it does not get less strange the further in you go.

Things that will not hold still

The machines here shift shape mid-fight, which makes reading them a different job to anything in the base game. There is a new boss waiting at the end of it.

Two weapons and a new trick

The Secateur is a ranged weapon with two firing modes, the Klusha is melee and can both slash and pierce. The polymer glove picks up Technostasis, which lets you interfere with time itself.
