About Unnamed Space Idle
Unnamed Space Idle is a sci-fi idle game about fighting an alien menace that has decimated humanity. You customize your ship with weapons and defenses that unlock progressively, choosing how to counter different enemy types. As you progress and prestige, you increase your power and make choices across more than 10 systems, each with mechanics that evolve and expand over time.
Ship upgrades
You equip weapons and defenses, choose modules that alter your power, and combine shards for upgrades. These choices affect how quickly you progress.
