About This Game

Your uncle is about to end the universe as you know it — and he thinks he's saving it.

Solar Engine is a procedurally generated top-down dungeon crawler set in a galaxy with a beginning and an end. Explore up to 80 planets generated from a single seed, survive their elemental hazards, dive into caves and Celestial dungeons, and race your uncle to claim five scattered Celestial Powers before he uses them to force the universe into permanent mechanical order.

Key Features:

  • A finite, seed-based galaxy — every planet is permanent and explorable forever, not endlessly regenerated

  • Deep elemental survival: manage heat, cold, radiation, toxicity, and psionic exposure with crafted gear and environmental tactics

  • The Wrench: Your one weapon and tool for the whole game, permanently upgraded (never replaced) with elemental mods that change combat and unlock new puzzle solutions

  • Build your ship node by node: swap layouts between combat, cargo, and scouting configurations

  • A living rival: Your uncle actively races you for power, corrupting planets and sending bounty hunters if you fall behind

  • Three joinable guilds, village progression, crew recruitment, and so much more!
