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.

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.
