Sphere TD

★ Sphere Td Is Free on App Stores ★

Try the game on app stores to get a sense of the deep tower buildcraft. You can easily transfer your progress on any platform via the in-game cloud sync!

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.

33 base mods x Mk (1-5) x Bside x 3 Perks x 5 Tiers x Adv Craft = Actually more than 1 mil but u get the idea.

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

P2W don't apply to the steam or mobile (or any) version. This image is just showing off cool explosions.

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.
