About this game

No ads! Unnamed Space Idle is an award-winning unfolding, sci-fi idle game that plunges you into a relentless battle against an alien menace that has decimated humanity.

Customize your ship with an array of progressively unlocked weapons and defenses, strategically tailored to counter specific enemy types. With a plethora of unfolding systems and abundant options, you'll face crucial choices as you steadily increase you power through progression and prestige.

A Myriad of Different Systems
Discover over 10 distinct systems, each offering unique mechanics that evolve and expand over time.
Core - Upgrade your Weapon, Defense and Utility cores with salvage gathered from enemies.
Compute - Improve your combat stats over time in traditional Idle Game fashion
Synth - Craft and improve modules and recipes to increase your power in various ways.
Void Device - Slot in void shards dropped by enemies for different combinations of upgrades.
Prestige - Unlock different ships, weapons, defenses and utilities.
Reactor - Feed void matter into your reactor to power various system boosts.
Research - Harness the research data obtained from different sectors to unlock various upgrades.
And More...

Impactful, Understandable Decisions
Choose wisely when equipping your ship with weapons and defenses, selecting power-altering modules, or determining the optimal combination of shards to use. The distinction between optimal and sub-optimal choices can significantly impact your progress. But while there are a lot of decisions to be made, they are all plainly understandable so that the optimum, or at least very near optimum decision making is within your grasp!

Consistent Progress and Unlocks
Well paced progression combined with the amount of different systems, upgrades and enemies, means something new is frequently just around the corner.

Fantastic Idle game. Multiple systems upgrade each other, new systems unlocked frequently, and old systems become permanent upgrades so you don't waste time doing the same thing repeatedly. No ads, 100% F2P. Spending money is optional and doesn't give you a huge advantage, so if you like the game support the dev. Updates still rolling out. It took me about 110 days to complete current content, and a new update was just released.

I will have to give the computer version of this a try, because the mobile version is not fun for me. The game throws too many terms and tabs at the player too quickly, and though there is a tooltip system, it doesn't really explain much besides just giving the player more information. More importantly, on a mobile device the buttons are so small that trying to navigate around the menu, turn tooltips on and off, all while the game is still trying to play... it was exhausting.

This game is sick! The text can be hard to read sometimes, so I gotta take a screenshot and zoom in to see what's up. The pacing is on point, just like a long form idle game should be. It kinda reminds me of ItRtG, at least in my opinion. I had a bit of an issue where I didn't get an achievement even though I had enough level boost for 5 minutes. Turns out, I had to disable the %VM automation to fix it. But other than that, I highly recommend this game to anyone reading this.
