Sky Defense

Sky Defense is a card-driven tower defense game set on floating islands. Build your deck, manage resources, and defend your Town Hall from waves of enemies.

Balance food, wood, and stone to place three building types: Production for resources, Shooters for range, and Units to block enemies. Protect your Town Hall through escalating rounds, facing a mini-boss on wave 5 and a final boss on wave 10.

Each round consists of 10 waves:

Wave 5 features a mini-boss

Wave 10 is a final boss fight

Survive the final boss to win the round. Lose your Town Hall at any point, and the run is over.

Cards are the core mechanic of Sky Defense.
Customize your deck before each battle:

Building Cards: Place resource buildings, ranged turrets, and unit spawners on the map.

Active Cards: Play instant spells for extra resources, card draws, or quick damage.

Passive Cards: Keep these in your hand to get constant stat boosts and additional buffs.

Careful deck management is essential. Synergy matters more than raw power.

Between battle rounds, spend your earned coins to prepare for the next threat:

Shop: Buy new buildings and spells to make strong combos.

Blacksmith: Combine two identical cards to unlock higher rarities and better stats.

Skill Tree: Unlock permanent run abilities that help you last longer.

Every choice impacts your survival in future rounds.

Sky Defense Is Built Around Replayability

Unlock starting builds through achievements. With random maps and new shop items every run, test your strategy and see how long your Town Hall can survive.
