Grid Forge TD

Grid Forge TD is a free flowing, maze building, incremental, tower defense game.

Maze building

Place tetrominoes to build your maze and shape the enemy path.

Tower defense

Stop enemies reaching the central tower. Place towers to stop them.

Tetrominoes can be stacked which provide height bonuses to the towers placed on them. Do you make the path longer with this piece you've been waiting for or do you build up your walls for bigger bonuses?

Elemental tiles

Unlock elemental tiles that allow you to imbue your towers with elemental damage. Slow your enemies with ice damage, or inflict damage on groups with chain lightning.

Meta progression

With each run you earn research points to buy upgrades. Improve your tower's strength, get more gold from your enemies, or unlock new abilities.

Prestige / Difficulty

Once you defeat wave 20 you unlock the next difficulty level. You'll face tougher enemies, and a wider variety of them, but you'll also earn more resources and be able to buy new upgrades like ice and lightning towers.
