Four years after the release of Psychonauts 2, developer Double Fine has returned with Keeper. It’s a third-person action-adventure charting the mysterious journey of a suddenly sentient lighthouse, and it’s launching for Xbox Series X/S and PC this October.

Keeper’s adventure across an atmospheric post-human world begins on a distant island in the shadow of a mountain, where a crumbling lighthouse still stands. For reasons currently unexplained, its ancient masonry suddenly gains life – and legs – whereupon it begins a journey toward the looming mountain, accompanied by a curious seagull.

Double Fine says the ensuing odyssey – a “story told without words” – features a mix of exploration, puzzle solving, and “unexpected departures from reality”. Along the way, the lighthouse learns to use its beam of light to affect the flora and fauna of the world, and to ward off mysteriously spreading tendrils. Its bird companion, meanwhile, is able to interact with ancient mechanisms to clear the path ahead.

“Together, these two unlikely friends set off together on an epic adventure,” explains Double Fine in its announcement, “an odyssey of mystifying metamorphosis, and a journey that will take them into realms beyond understanding. ”

And if that’s piqued your curiosity, Keeper launches for Xbox Series X/S, PC, and Game Pass on 17th October this year.
