About Islets Defense
Islets Defense is a turn-based tower defense game about managing resources and building an efficient village to support your towers. You defend against slimes, explore a map hidden by mist and advance through stages to unlock different biomes.
Plan your turns
Each turn, you choose one of four cards, each of which performs a different action. Their order matters: the rightmost card has a stronger effect. After you use a card, it moves to the leftmost position and the others shift one place forward, so you need to make effective use of all four actions over time.
Build your defense
Place towers strategically, feed them with food and upgrade them using wood and stone. Buildings offer different upgrade options, and your choices can work together with your positioning strategy. Chests and stage modifiers create further strategic opportunities, with unique towers and upgrades to discover.
Explore the stages
The map begins unexplored beneath a covering of mist. Use the exploration action to find resources, reveal areas that give your attack towers visibility and uncover hidden treasures. The campaign has 15 stages with distinct modifiers, level designs, biomes and challenges. Completing stages and challenges earns diamonds and feathers, which unlock biomes.
Buildings and tiles
- More than 25 building structures, each with its own abilities
- Six upgrade options available for many buildings
- 20 tile types scattered throughout the stages, each with its own interactions
- More than 10 hours of playtime
