Skyward Bastion

Skyward Bastion is a roguelite tower defense game set on floating islands above the clouds. You build a Bastion, expand its territory each round and defend it from waves of enemies. Procedurally generated maps, challenges and upgrades vary between runs.

Expand the map

Each expansion reveals new procedurally generated terrain, requiring you to adapt your defenses. You may also find powerful pylons that enhance your towers and create new strategic options.

Defend your Bastion

Place and upgrade towers to protect your Bastion, choosing upgrades and combinations to shape your defenses for each run. The game has five unique towers, each with dozens of upgrades, and over 100 unlockable upgrades.

Face enemy factions

The Early Access content includes 25 rounds of enemies from two factions. Threats include skeletons, resilient zombies and other enemies with distinct abilities. Each faction has a final boss, for two bosses in total.

Progress between runs

You earn experience and unlock permanent upgrades that increase your defensive power and expand your strategic options for future expeditions. The game’s content is set to expand during Early Access with additional towers, enemies, upgrades, bosses and mechanics.
