HOLLOWSIM: Industrial Voidline Defense is a retro-styled space strategy and simulation game about building, defending, and expanding a fragile industrial foothold in a hostile sector. Command ships in real time, mine resources, construct and upgrade structures, expand into new sectors, manage logistics and trade, and prepare your operation for increasingly dangerous attacks.
Build up your fleet and industrial network while balancing growth against survival. Different ships, structures, factions, contracts, and threats create multiple ways to approach each run, while difficulty settings let you tune how aggressively the void pushes back.
Features include real-time fleet control, resource gathering, base construction and upgrades, sector exploration, trading and logistics, faction interactions, tactical combat, persistent progression through your expanding operation, and multiple difficulty levels. The game also includes guided tutorial content to introduce its major systems before you move into the broader sandbox.
Steam currently lists 5 Nov 2026 as the release date.
