SOLUM is a floating-island factory sandbox. Extract Sol and automate production across an expanding Island-Network. Build networks, route goods, and keep your islands stable against the pull of a collapsed star.

SOLUM is a sandbox factory-builder set on drifting floating islands orbiting a collapsed star. Harvest Sol and tame its energy, and stitch a working ecosystem together before the Island-Network tears itself apart.Design modular production lines, automate everything. Every decision pushes the system toward stability… or a beautiful, catastrophic chain reaction.<h2 class="bb_tag" >Build. Automate.

The focus right now is core factory gameplay, logistics, and island management. Additional systems, including combat-adjacent challenges and some special modes, are being explored and will be shared when they’re ready.
