Robo Siege TD

Defend against relentless robot armies in a 3D sci-fi tower defense game where clever tower placement earns automatic upgrades. Each tower rank has more automatic upgrades than the last (up to 3 ranks). Then build factories to unlock even more powerful tower enhancements after the 3rd rank. Can you unlock the silver and golden towers? Experiment with tower placements, upgrades and factories as the robot invasion unfolds. It's up to the player to build towers at strategic locations in order to destroy the enemies so as to make different towers work together. Many different environments and effects brings each world to life.

Tutorial available on first level.

High Replayability

10 Levels in the main campaign with 3 difficulty levels each. 5 alternative ways to play.

NEW (August 2026): 10 bonus levels will be available at launch for a total of 20 levels.

Many Enemies

12 different enemies. Enemies can have shields and armor. Specific towers are more efficient against shields. Stronger but slower towers are better against armor. Three utility bots. One can heal other robots. One is extremely fast. And one gives shields to nearby robots.

Specific towers can counter each type. Short circuit (electrocution) tower does short work of shields. The slower but more powerful Sniper tower is great a destroying armor. Laser towers are great at getting rid of unprotected enemies. EMP tower slows down enemies to allow more damage. Machine gun is great on fast but weak enemies that may slip through otherwise.

Upgrades

This game is a partial incremental tower defense game with automatic upgrades and further upgrades beyond rank 3 of most towers. An incremental game is one where you achieve many upgrades in quick succession during the entire gameplay. Each tower has 3 ranks that the player can upgrade to directly (2 upgrades each). Each of those ranks have automatic mini upgrades as they achieve a certain amount of damage. Each rank has more mini upgrades than the previous rank. Gain enough gold to unlock the Factory tower and reveal another layer of upgrades. Can you unlock the golden tower?

Towers

10 towers with 3 ranks each with more upgrades to be discovered in game (with the factory tower). Each tower serves a different purpose that the player can mix and match to optimize their strategy. Get automatic mini upgrades for well placed towers. Every tower evolves as it fights.

New (August 2026): A new set of 3d models of the existing towers will be available at launch. The original set will still be available in game as an option.
