Island Siege: Tower Defense

100 waves. 10 chapters. Real boss fights. Build your island, train your army, and hold the line. Free to play, no ads, and it works fully offline.

This small island was once peaceful — full of fruit trees and the laughter of villagers. Now the raids have begun, and it's up to you to defend it.

Island Siege is a pixel-art island-defense strategy game. Build your base, train your army, and hold the line across a 100-wave, 10-chapter campaign that only gets harder the longer you survive.

FEATURES

• 100-Wave Campaign — Ten chapters of escalating raids, each one tougher than the last, building to a true endgame test.

• Build & Upgrade — Place barracks, archery ranges, and defenses. Grow your economy to keep pace with the enemy.

• Epic Boss Battles — Face a growing roster of monstrous bosses, each with unique attacks, plus a finale encounter with real narrative stakes.

• Rival Invasions — Rival factions land on your shores mid-campaign. Pay tribute to keep the peace, or fight them for the glory.
