Enormous Swarms of Physics-Based Enemies.

Physics based enemies. Enemies will swarm, pile, and push through your defenses.

Up to One Million enemies alive at once, all trying to get past your defenses.

Huge Enemy Variety

Over 3 dozen enemy types with unique behaviors and skills to create different challenges to overcome. Armored Behemoths that shrug off smaller hits, Clerics that heal allies, Hurlers that throw their own allies as projectiles, Elite troops that hunt down your soldiers, tiny Mites that jump over walls, exploding Bombers, and many more unique enemies await you.

Dozens of Tools at your disposal.

Over 60 different towers, traps, units, and spells to combine to decimate your foes.

Build towers to rain lead or explosions. Lay traps to whittle down enemies in choke points. Build walls to block off pathways and create defensible positions. Recruit units to bring the fight directly to the enemy on the ground. Cast spells to manipulate, debuff, or kill your enemies.

Tech Tree and Campaign

Beat over 50 maps in a campaign and complete challenges. Use the Tech tree to discover and power up your arsenal as your campaign progresses. Unlock new towers, units, and spells, or upgrade the ones you have with new capabilities. Find specializations and synergies to overcome any challenge. Respec at any time, and save your favorite tech presets to use later.
