Frontier defense
A tower defense game on generated industrial battlefields. Armored drones march along a winding service track, and you decide where your cannon turrets stand. Then take the fight across a galaxy of 50,000 drone worlds.
How it plays
- Every outpost run generates a new battlefield with a guaranteed enemy route.
- Start with one free turret and choose its position; a coverage ring shows exactly what it will reach.
- Destroy drones and clear rounds to earn credits for more turrets.
- Hold out through four rounds, then bring down the Drone King, a towering six-legged boss with a crown of spires that enrages as it weakens.
- Earn up to three stars for each victory, and coins to spend on cosmetic turret finishes.
Drone Universe
- Explore a spiral galaxy of 50,000 drone worlds, from the calm rim to the lethal core.
- Every world shows its toughness and how many rounds it holds, and a crown marks the worlds ruled by a Drone King.
- Eight kinds of world, each with its own ground, light and weather: dunes, glaciers in snowfall, magma flats raining embers, toxic swamps under acid rain, crystal fields, storm worlds, rust deserts and glowing abysses.
- Swift drones, swarms and armored drones join the fight.
- Liberate worlds to keep your best stars and earn coins, then head for the next world on the way to the core.
