Islets Defense is a turn-based tower defense game focused on resource management in which you build a small and efficient village to support your towers and secure victory.

A turn consists of executing one of the four available actions, each with its own unique functionality. The order of the cards plays a key role, with the rightmost card offering a stronger effect. After completing your turn, the chosen card moves to the leftmost position, pushing the others one step forward. Consistent and efficient use of all four cards is key to building a solid defense.

Allocate your towers in strategic positions, sustain them with food, upgrade them with wood and stone, and ensure a strong defense against the slimes. Chests and stage modifiers will offer new strategic opportunities, with unique towers and various upgrades to explore.

Each building has different upgrade options for you to choose from. Build the most efficient village by making smart decisions that synergize with your positioning strategy!

The mist has covered your entire kingdom! You start the game with an unexplored map, ready to be revealed! Use the exploration action to reach new resources, gain visibility for your attack towers, and discover hidden treasures!

Advance through stages, complete challenges, and earn diamonds and feathers to unlock and face different biomes! Islets Defense is the game for those looking for a classic tower defense experience mixed with the chilling vibes of a resource management game, all wrapped up in easy-to-understand mechanics filled with creative possibilities.
25+ different building structures, each with their own unique abilities.
A 15-stage campaign featuring distinct modifiers, level design, biomes, and challenges.

10+ hours of playtime!
Islets Defense for PC starts at €0.34 (€0.72 with fees) at Kinguin, a Steam key, which is 89% under the €6.82 (no fees) it costs on the official store.
We have never recorded it cheaper than this.
That €0.34 (€0.72 with fees) already includes the OCTGOC10 coupon, so apply it at checkout or the store will show you a higher price.
Just 5 stores stock it, 5 offers in all, so there is little here to push the price either way.
That €1.38 (€1.90 with fees) key is at one of its best prices.
Worked out from 611 daily records of the Steam Key for Islets Defense across 5 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
All 5 offers are Global, so the code redeems on any account no matter where it was created.
One listing is worth ignoring: the Steam key that Steam has at €6.82 (no fees) is more than 9 times the cheapest offer and is not what this game costs. The number to work from is €0.34 (€0.72 with fees) at Kinguin.
