About Idle Stellar
Idle Stellar is about defending the galaxy from an impending invasion and bringing order to its outer borders. You gather resources, fight local factions, develop your ship and recruit crew members who can help even while you are offline.
Gather and fight
Mine asteroids for metals and minerals, harvest space clouds for exotic gases and chemicals, and salvage wrecks for spare parts and lost artifacts. Battle local factions for loot and experience, choosing gear to counter your enemies and using special abilities to turn fights in your favor.
Develop your crew and ship
Craft resources, fuse chipsets and unlock scientific advancements. Upgrade ship modules to improve gathering and combat, and level up crew members to unlock mechanics and perks. You can prioritize upgrades for active play, idle play or a mix of both.
