About this game

The star is failing and the system is coming apart. You're the last salvage operation still running.

Umbral Idle: Last Salvage is an incremental idle game and colony builder. Tap to gather Salvage, then build Drones, Reactors, Archive Scanners and Static Coils that keep producing while you're away. Each resource feeds the next, so a well-built chain multiplies everything above it.

Every run ends in the Collapse. Trigger it early and start again stronger, or hold on: the longer a system runs, the more unstable it gets, and the more it pays when it finally goes. You keep Iso-Cores, permanent power that makes every future run faster, and spend Residuum in the Tech Archive on automation, new zones and stronger production.

- Push out into the Debris Belt: three stages with timed Salvage Runs, missions and push-your-luck crew recovery operations.

- Discover the Research Lab, a second, slower prestige system that runs from Matter all the way to Solar Systems.

- Earn offline. Return to a summary of everything your colony produced while you were gone.

- 57 achievements, Google Play leaderboards, a 28-day daily reward calendar, cloud save through Google Play Games.

- Designed for short sessions. No characters to collect, no gacha. Progress is in the numbers.

- Ads are optional rewarded bonuses only, and a single purchase removes them for good.

- Playable in English, French, German, Spanish, Portuguese and Simplified Chinese.
