About this gameFull description from Steam
Unnamed Space Idle is an 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. 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. Warp - Warp to special enemy locations to harvest essence for upgrades in a massive tree. And More... 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! Well paced progression combined with the amount of different systems, upgrades and enemies, means something new is frequently just around the corner.
