SteamAbout 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:
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:
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.
