About this game
Rustlight is an idle survival game and colony builder set on a rust-red planet. Lead a small crew, build your base and keep everyone alive through day and night — even while you're away, your colony keeps working.
Mine ore, drill ice for water, grow food and raise solar panels. Then get ready for the night: the panels go dark, and your batteries, your reactor and your engineers are all that stand between the crew and the cold.
MANAGE YOUR CREW
Assign colonists to jobs — miners, farmers, engineers, scientists — and keep your buildings staffed: a module with nobody on it runs at half speed. Where you put your people is a real decision.
RESEARCH AND HARD CHOICES
Unlock 11 technologies and face 13 events with real consequences: dust storms, meteor showers, blight in the greenhouses, volunteers asking to land when there is no room for them. Every choice has a cost.
NEW ERAS, NEW RULES
Light the Terraforming beacon to start a new era, then leave on a new expedition with your relics and spend them on 16 permanent upgrades. Each era brings planet conditions that change the rules — cold, dust, long nights, low gravity, spores and more — so every run plays differently.
FEATURES
• Idle and incremental progress with real strategy: a day and night cycle that matters
• Base building with 12 modules and 4 crew jobs
• Goals every few minutes, plus daily goals and a daily supply crate
• Offline progress up to 8 hours: come back to a colony that kept working
• Prestige with expeditions, relics, permanent upgrades and generated eras
• Animated pixel-art colony with original music
• Free to play: ads are only optional reward videos you choose to watch — no banners, no forced ads
• No account needed, the game works offline, progress saved on your phone
• English and Italian
