Koop Idle Slayer PC

Start from Nothing

Every Slayer begins with nothing.

Jump, collect coins, defeat enemies, and slowly grow stronger. What starts as a simple experience gradually evolves into a much deeper adventure filled with progression systems, upgrades, challenges, and secrets waiting to be discovered.

As you progress, you'll earn Souls to strengthen your Slayer, unlock new abilities, and discover mechanics that completely change the way you play. Whether you're actively playing or progressing while away, there will always be a new goal to pursue.

Explore Countless Dimensions

Travel through a wide variety of dimensions, each with its own enemies, resources, and challenges.

Every dimension offers unique materials that can be obtained by defeating enemies. These materials are essential for crafting powerful items, unlocking upgrades, and continuing your journey toward greater strength.

With every new destination, you'll encounter different creatures, discover new strategies, and find more ways to progress.

Customize Your Adventure

Unlock a wide variety of skins for your Slayer as you progress through your journey.

From outfits inspired by different dimensions to special characters earned through challenges and events, there will always be new appearances to collect and show off your achievements.

Endless Progression

Idle Slayer is built around constant growth.

Invest your Souls in a massive Skill Tree to unlock new mechanics and improve every aspect of your adventure. Gather materials to craft increasingly powerful items and obtain Divinities that can completely transform your gameplay experience.

You'll also discover the Armory, where powerful equipment can be unlocked, upgraded, and equipped to further customize your Slayer and push your progress even further.

More Than an Idle Game

The Village offers a completely different way to experience Idle Slayer.

Explore freely, interact with characters, uncover secrets, and follow a story that continues to expand with new updates. The Village connects much of the game's content and turns the adventure into something far greater than simply collecting resources and upgrades.

Put Your Skills to the Test

Beyond the main progression, you'll find several minigames with unique rewards.

Overcome obstacles in Bonus Stage, search for treasure in Chest Hunt while avoiding dangerous Mimics, climb Mt. Otto in Ascending Heights, or swing through challenges in Grapple Run.

Each minigame offers different mechanics and additional opportunities to earn Souls, collect resources, and obtain special rewards.

With over 650 achievements, multiple progression systems, offline gameplay, regular updates, and the ability to continue your adventure on both PC and mobile using the same save, Idle Slayer offers a journey that always has something new to discover.
