BUILD YOUR TOWERS

You will need to build EVERY tower. No presets.

SPAM THE PROJECTILES

Defend your base, ideally by spamming hundreds of projectiles down the sphere's path.

MAKE YOUR CHOICE

Pick ModCards for a small (or legendary) boost to your base or drone tower.

1 TOWER = 1,000,000 BUILDS

After action report means building more towers. No sleeping on the job, cadet!

BIGGER SPHERE, BIGGER PROFITS

Destroy spheres for profit or just mine ores. Are your towers are up to the job?

CRAFTS MODS TO THE MAX

Got rich from mining? Here's how to spend your gold. More theory-crafting and actual crafting.

DEFEND, BUILD, MINE, IDLE... PLAY HOW YOU WANT.

The Galatium Academy allows Cadets plenty of freedom and free time in the Sphere Simulacrum.
