This is a complex but rewarding TD. Featuring high replayability (Top 100 cadets have spent 110+ hours), deep RPG builds, with roguelite and incremental elements.

You will need to build EVERY tower. No presets.

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

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

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

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

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

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

Join the Galatium Academy (for profit organization) for a career in Sphere TD!
