Bastion Keep: Tower Defense

Build your towers. Hold the road. Defend your kingdom—offline.

Bastion Keep brings 60 campaign missions across 11 distinct environments, from lantern-lit villages and stormy cliffs to mountain monasteries, luminous marshes and a canyon observatory. Discover a different battlefield early in your journey, then return with a new plan.

BUILD YOUR DEFENSE
Combine Archer, Cannon, Frost, Arcane, Ballista, Poison and Storm towers. Each has four upgrade levels that change its appearance and strength. Cover bends, choose your choke points and adapt to armored enemies, flyers and healers.

FIND YOUR CHALLENGE
Face five bosses. Choose Easy, Medium or Hard, with separate star records for each difficulty. Replay missions to refine your tactics and earn royal coins. Choose from five castles as you progress.

THE CAMPAIGN, WHEREVER YOU PLAY
No ads. No in-app purchases. No account required for the campaign. All campaign content is included in the download and works offline on your Android device.

Some mission names and older game text remain in English.
