About Islets Defense

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.

How much does Islets Defense for PC cost right now?

Islets Defense for PC starts at €0.78 at Eneba, a Steam key, which is 92% under the €9.75 it costs on the official store.

That €0.78 already includes the GOCDKEYS10 coupon, so apply it at checkout or the store will show you a higher price.

Just 5 stores stock it, 6 offers in all, so there is little here to push the price either way.

That puts it 73% under its average of €2.91 since 2025, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for Islets Defense now or waiting?

That €1.09 key is at one of its best prices.

  • Those €1.09 are 58% below what it usually costs, measured on the store price.
  • Only 4 stores sell the Steam Key, and with that little competition the price barely moves.
  • Not counting today, only 9 days out of the 309 days on record were this cheap or cheaper; the lowest it has ever cost is €1.03.
At this price it is worth buying the Steam Key now: what you stand to gain by waiting is a few euros, and it is not guaranteed.

Worked out from 474 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.

Can you activate Islets Defense in US?

5 of the 6 offers work on US — the Global ones plus the ones issued for your own region.

Why is there such an expensive Islets Defense offer?

One listing is worth ignoring: the Steam key that Fanatical has at €9.75 is more than 12 times the cheapest offer and is not what this game costs. The number to work from is €0.78 at Eneba.

INFORMATION ABOUT Islets Defense FOR PC


Islets Defense is a turn-based strategy game that combines tower defense with resource management elements. The goal is to develop an efficient village that will strengthen your defenses against constant threats. Every decision you make affects the balance between expansion, improvement, and protection, in a dynamic that requires planning and long-term vision.

Each turn, you can choose one of four available actions, presented in the form of cards. The impact of each action depends on its position in the row, with the card on the right being the most effective. After each turn, the card used moves to the far left, thus changing the layout for the next turn. This system requires intelligent and balanced use of all actions to maintain a consistent strategy.

Defensive towers are placed in key locations on the map and must be supplied and upgraded using resources such as wood and stone. As you progress, chests and modifiers appear, offering new ways to approach challenges and unlocking special towers and additional strategic benefits.

The village you build will be critical to your success. Each building you construct brings with it different upgrade options, so carefully choosing your buildings and their development is essential to achieving a structure that boosts both your defensive capabilities and your economic development.

The game map begins covered in dense fog, and you must explore to reveal its contents. By doing so, you'll not only discover new resources and enemies, but also open up new areas to place towers, gain visibility on the battlefield, and find hidden treasures that can make all the difference in your chances of victory.
