Breachline

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. 15 TOWERS, 241 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 - 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 - 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 241 upgrade nodes across 16 trees into your favorites and reshape how they fight. EVERY ENEMY HAS A COUNTER 14 enemy types and 6 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 - 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.
