Null Keeper

Game premise and overview

Null Keeper is a sci-fi lair-builder for PC that draws inspiration from classic dungeon-management games. Players take control of an asteroid containing a Void Core at its center and must design and manage a complex underground base. The goal is to protect the Void Core from increasingly difficult waves of attackers known as the Vanguard.

Building and resource management

You dig into the asteroid to expand your lair, claiming floor space to construct various rooms essential for your operation. Available structures include vaults for storing resources, habitats for creatures, BioSynth labs, and Combat Simulators. Each room you build requires floor space, which you can only gain through careful digging and planning. Where you place the Void Core in relation to your defenses is a critical decision that affects your strategy.
