DEFEND THE LINE
The swarm is coming in 50 escalating waves. Your base is the last thing standing between them and the breach. Place your towers, read the enemy, and adapt — or watch the line collapse.
16 TOWERS, 254 UPGRADES
This isn't a "build the same turret x10" defense. Every tower plays differently:
Laser & Plasma — precision damage and splash
Mortar & Salvo — area saturation and multi-target barrages
Arc Coil — chain lightning that jumps between packed enemies
Railgun — a line-piercing sniper that punches through columns
Flak Cannon — air-only burst fire that shreds the flyers ground turrets cannot reach, and can force them down onto the road
Pyro — stacking burn that hard-counters regenerators
EMP — strips shields and locks down tech
Acid — corrodes armor so everything else hits harder
Gravity Well — drags a whole column onto one point and pins it there for your splash towers
Minelayer — seeds the road with mines, and every blast hits the whole column around it
Scanner — reveals cloaked, burrowed and blinking units so every tower can hit them
Beacons — project damage / range / fire-rate auras that supercharge nearby towers
Pour 254 upgrade nodes across 17 trees into your favorites and reshape how they fight.
EVERY ENEMY HAS A COUNTER
17 enemy types and 7 multi-phase bosses, each built around a mechanic you must answer:
Armored, shielded, and self-healing units
Flyers that ignore ground-only turrets
Burrowers, cloakers and blink-teleporters that vanish from your sights
Splitters that multiply on death
Sweepers that defuse your mines
Dropships that unload ground troops, and armored airships that bomb your base
A flying carrier boss that launches squadrons, then carpet-bombs your towers
Bosses that fortify mid-fight and grow their own health bar
Bring the wrong loadout and you stall. Bring the right answer — Scanner for the invisible, AA for the skies, Acid for the armored — and you cut through.
