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. 14 TOWERS, 229 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 Pyro — stacking burn that hard-counters regenerators EMP — strips shields and locks down tech Acid — corrodes armor so everything else hits harder Beacons — project damage / range / fire-rate auras that supercharge nearby towers Pour 229 upgrade nodes across 6 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. ONE TIGHT RUN A full campaign is ~45 focused minutes: 50 waves, 10 boss encounters, real decisions every round. Calm, readable visuals even at 60-enemy swarm density. Easy to learn, brutal to master.
