About this game

NooSphere is a tower-defense game played across the surface of a slowly rotating "sphere of mind." Spin the globe, claim territory, and ring the lanes with turrets and walls to hold back columns of marching Philosophical Zombies before they reach your CPU core.

Power is everything: reactors feed your grid, fabricators push your blue territory outward, and purifiers contain a creeping green virus that feeds the enemy. Build up until you can clear a 2×2 pad, deploy a Transmitter, and "download" the sector to deactivate it.

With a hand-spun 3D planet board, a hacker-flavored roster of cores to breach (0xC0FFEE, 0xDEADBEEF and friends) and a containment-and-conquer objective layered over classic defense, it's a fresh spin on the genre.

How to play

  1. Drag or use WASD to rotate the sphere and survey the lanes.
  2. Pick a building (1–8 or the mouse wheel) and click a claimed (blue) cell to place it.
  3. Build reactors for power and fabricators to expand your territory outward.
  4. Ring the enemy's path from the red spawn to your CPU with turrets and walls, and purify the virus.
  5. Clear a 2×2 pad, press T to deploy the Transmitter, and defend it through the download to win.
