Press release:
Wiesbaden, Germany – April 28th, 2026. Assemble Entertainment, in partnership with Norwegian indie developer Lugn Games, has announced that the much-anticipated Kioku: Last Summer will launch on 28 May 2026 on Steam. This idyllic escape is where friendship, mystery, and discovery will unfold across a summer you will never forget. Lose yourself in the gorgeous, smooth animation, reminiscent of your favourite 90s Japanese cartoons, and witness a genuine, heartfelt tale told over the course of one incredible summer.

Let your adventure begin

You play as Asti, a curious youngster who arrives on the island of Kioku to begin a new life with her father. You’re eager to explore this island paradise and make new friends, but one boy keeps his distance. Why?

Uncover a tale of laughter, tension, and quiet moments that reveal evolving relationships and shared adventures. Asti will discover that every friendship has its own story to tell.

If you loved Wanderstop, Spiritfarer, and Oxenfree, this is definitely one to watch.

Staying out for the summer

Bask in childhood nostalgia as each in-game day brings something new. Help local residents, solve mysteries, and reveal secrets through a series of story-driven quests and tasks.

Battle your friends at Marubi, a collectible marble game inspired by your childhood favorites. Build up a team of unique creatures, each with distinct stats and abilities, and compete against your new friends. You’ll also try your hand at crab fishing – catch a variety of crabs, discover rare finds, and trade mysterious Crab Pots for valuable items to help you on your journey.

Kioku is a world of hidden wonders

A secluded island just 45 minutes from the mainland, Kioku is inspired by the Scandinavian and Japanese countryside.

Explore Kioku’s many intriguing spots:

🏘 The Town – bustling streets, quirky shops, and whispers of untold stories.
⚓The Pier – where the waves sparkle with secrets and the horizon teases adventures beyond.
📚The School – a place of knowledge… and hidden curiosities lurking behind every corner.
🌲The Forest – a maze of towering trees, rustling leaves, and the occasional glimmer of enchantment.
⛰️Mt. Tin – climb if you dare, and you might find a view that changes the way you see Kioku forever.
🍎Jodd’s Apple Farm – sweet treats, playful animals, and perhaps a story or two tangled in the orchard.
🏝 Murt’s Island – a tiny isle with big mysteries, only reachable by those brave enough to cross the waters.
⛩️The Mysterious Shrine – ancient, quiet, and alive with whispers of the past… Some say the shrine has a mind of its own.

Every step you take on Kioku could lead to friendship, mischief, or magic as you unravel a story of friendship, change, and self-discovery and unearth hidden secrets at your own pace in this cozy adventure.

Your unforgettable summer begins on 28 May 2026.
