A tower defense where the enemy learns along with you.

The Mindswarm is no ordinary stream of monsters. It watches what you fight it with — and adapts. Lean too hard on Fire, and from wave 11 it builds up Fire resistance — up to 45% on Normal, 90% on Hard — while sending waves in the element your towers do least against. Rebuild, and the swarm follows. Every tenth wave is a boss wave: Shield Bosses, Spawner Bosses and, on Hard, mutated bosses armored against the element that hit the last boss hardest.

The AI Recon panel makes its thinking visible: your main element, the resistance it is building and the counter wave it is planning — live, while you play. The game warns you before every counter wave, heavily armored enemies shimmer, and after the game the swarm analysis shows how it read you.

⚔️ Six elements, twelve towers, two totems

• 6 elements — Fire, Water, Plant, Electric, Earth and Rock — each strong against some and weak against others
  
• 6 base towers with their own element effect: burn, vulnerability, slow, stun, splash, knockback
  
• 6 combo towers, fused from two base towers right on the board: Volcano, Storm, Swamp, Steam, Railgun and Poison — dealing damage of both elements, each with a signature such as chain lightning, eruption, roots or poison over time
  
• 2 support totems: Power (+25% damage, +15% speed) and Focus (+30% range) for all adjacent towers
  
• 3 upgrade paths — damage, speed, range — with 3 tiers each, group upgrade with a double-click
  
• 6 target modes per tower or for all, sell to rebuild — at full price in the rebuild phase after every 20th wave

🧠 An enemy that thinks along

• Counter waves and resistance against your main element — never fully immune, never to be ignored
  
• Extra counters on Hard: a Totem Hunt with saboteurs that switch off totems as they pass, or an Air Swarm when too many flyers get through
  
• Enemy variants: Runner, Flyer, Healer, Splitter, Tank and Saboteur — every wave in one of the six elements
  
• A Shield Boss whose energy shield must fall first, and a Spawner Boss that keeps calling in adds
  
• Wave preview with element, variant and HP of the next wave
  
• Endless waves — how far can you get?
