Sphere TD: Build & Mod Towers

Sphere TD is a tower defense game with one difference: there are no preset towers. You build every tower yourself by combining mods to spam more projectiles.

UNIQUE FEATURES

- Build & mod every tower. There are no preset towers.
- Defend each map with 5 towers. Max them out and spam more projectiles.
- Split your shots, bounce, multiply, shock, burn. The build is up to you.
- Your base can fly, towers and all. Explore the maps and mine ores.
- Research and craft mods. Just don't run out of energy.

WHAT IS IN THE GAME

- 41 towers, each with its own grid layout and function
- 33 mods, each with tiers, MK upgrades, a B-Side function, and 3 perks, for over a million tower builds
- 50 hand-crafted maps with three objectives each
- Endless mode after map 50, plus map-specific challenges
- A research tree, mod crafting, and a trader
- Spheres that scale into elites, bosses, armored, shielded, cloaked and flying
- Offline play, with cloud sync and leaderboards
- Cross platform: mobile and desktop
