A Shelter in Spacetime
Dmitry Dornichev
Sergey wakes up in a French hospital surrounded by hordes of zombies — with nothing but a baseball bat and his own personal shelter in spacetime: a pocket dimension that serves as his base in a multiverse-spanning apocalypse. From escaping Paris to reaching Berlin and back to Mother Russia, Sergey defends and grows his shelter against zombie generals, Sovereign armies, rival shelter-holders and invading aliens across the Spacetime Ocean.
Progression: LitRPG apocalypse progression centered on Sergey's personal extradimensional shelter in spacetime. Advancement is explicit and structural: the shelter itself levels up and expands (powered by the World Heart, whose glow draws both allies and enemies), Sergey earns system rewards and loot from defeating escalating foes (zombies, zombie generals, Sovereign armies, rival spacetime inhabitants), learns new skills and spells, hires inhabitants for the shelter, and extends his reach across planes and the Spacetime Ocean — from a lone survivor's bolt-hole to a multidimensional nation-scale power base.
