Sergey travels to an unfamiliar planet to save his spacetime shelter, finding another world devastated like Earth. His mission goes awry while conditions on his home planet continue to deteriorate, creating dangers on both sides.

Having overcome a zombie army, Sergey prepares to continue toward Berlin. The World Heart makes his shelter shine across the spacetime ocean, attracting other inhabitants and turning his refuge into an increasingly conspicuous destination.

Sergey juggles managing his spacetime shelter with rescuing others and collecting whatever resources he can find. The demands keep multiplying, leaving his long-delayed journey to Berlin uncertain as survival competes with his appetite for loot.
