Unnamed Space Idle

Unnamed Space Idle is a long sci-fi idle game. Aliens have nearly wiped out humanity, and your ship fights their endless waves. You pick weapons and defenses that unlock over time, and choose them to beat specific enemy types. The game keeps opening up new systems, more than 10 of them. Salvage upgrades your weapon, defense and utility cores. Compute raises combat stats over time the classic idle way. Synth crafts modules, void shards slot into a device for different upgrades, and a reactor burns void matter for boosts. Research, warping to special enemy sites and a large essence tree add even more. Prestige unlocks new ships, weapons, defenses and utilities. There are plenty of choices, but the game keeps them easy to understand, so you can work out a near-best setup yourself. It's free to play and has been in Early Access on Steam since July 2023, and it still gets updates. It suits idle players who want a deep game to stick with for a long time.
