About this game
Shoot. Upgrade. Die. Repeat.
Endless Void: Idle Tower Defence, a minimalist incremental game where your only objective is to hold the line against mathematically infinite waves of enemies.
Start with a single, basic cannon. Through persistent upgrades, deep research trees, and raw firepower, evolve your lone tower into a cosmic fortress capable of tearing the fabric of space and time. Whether you want to actively manage your tower, or sit back and let your automated drone swarms do the heavy lifting, the progression never stops.
Devastating Cosmic Legendaries:
Go beyond simple bullets. Summon screen-clearing Orbital Strikes, deploy gravitational Black Holes and chain massive Lightning strikes.
Endless Incremental Scaling:
Push through Normal, Hard, and the infinitely scaling Void Mode. As the enemies get tougher, your tools get exponentially more devastating.
The Forge (Deep Crafting System):
Slay bosses to harvest Scrap. Craft, enhance, reforge, and salvage randomized loot with unique primary and sub-stats to min-max your tower's build.

The Laboratory (Offline Progress):
Your research never sleeps. Queue up permanent global upgrades, unlock mega-projects, and gain resources even while the game is closed.
Combat Drone Bay:
Automate your defence. Deploy Aegis shields, Midas drones for boosted economy, or Kamikaze bombers to handle the swarms while you focus on the big picture.
Massive 600+ Talent Tree:
Shape your ultimate build through an expansive constellation of over 1000+ passives and game-defining Keystones that completely alter your playstyle.


Minimalist Retro Aesthetic:
Clean vector graphics, a nostalgic CRT-monitor glow, and a thumping synth-wave inspired audio engine keep the action readable even when the screen is filled with chaos.

Will you reach the Singularity? The swarms are infinite, but so is your potential. Wishlist now, join the community, and start theory-crafting your ultimate build!
