Sphere TD is a deep logic tower defense game where you build every tower from scratch. No preset towers! Route mods through grid layouts to fire projectiles: split, bounce, chain, pierce, multiply them. A true one tower with a million build combinations.
Built for players who enjoy optimization, min-maxing tower stats, theory-crafting builds, factory-style routing puzzles, and roguelite choices.
Highlights:
- Build & mod your towers and projectiles! Nothing is premade!
- Logic & puzzle routing: pack grids, optimize projectile paths, min-max every build.
- 39 towers with unique layouts and functions.
- 33 mods, each with tiers, MK upgrades, a B-Side function, and 3 unique perks
- Research, advanced mod crafting, and long-term progression.
- Tower inventory and energy management.
