Breachline

DEFEND THE LINEThe 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 UPGRADESThis isn't a "build the same turret x10" defense. Every tower plays differently:Laser & Plasma — precision damage and splashMortar & Salvo — area saturation and multi-target barragesArc Coil — chain lightning that jumps between packed enemiesRailgun — a line-piercing sniper that punches through columnsFlak Cannon — air-only burst fire that shreds the flyers ground turrets cannot reachPyro — stacking burn that hard-counters regeneratorsEMP — strips shields and locks down techAcid — corrodes armor so everything else hits harderGravity Well — drags a whole column onto one point and pins it there for your splash towersScanner — reveals cloaked, burrowed and blinking units so every tower can hit themBeacons — project damage / range / fire-rate auras that supercharge nearby towersPour 241 upgrade nodes across 16 trees into your favorites and reshape how they fight.EVERY ENEMY HAS A COUNTER14 enemy types and 6 multi-phase bosses, each built around a mechanic you must answer:Armored, shielded, and self-healing unitsFlyers that ignore ground-only turretsBurrowers, cloakers and blink-teleporters that vanish from your sightsSplitters that multiply on deathBosses that fortify mid-fight and grow their own health barBring 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.ONE TIGHT RUNA full campaign is ~45 focused minutes: 50 waves, 10 boss encounters, real decisions every round.
