Cairn

Cairn is a 2026 simulation adventure video game developed and published by The Game Bakers. Players control Aava, a professional mountaineer who seeks to summit the mysterious Mount Kami. While her journey is mostly solitary, she encounters other climbers and inhabitants on the mountain and uncovers remnants of past expeditions along with a long-lost civilization. As a simulation game, players manually control each of Aava's limbs. The game also features elements commonly found in survival games, with players being tasked with managing Aava's hunger, thirst, and temperature. It also features a weather system and a day-night cycle, both of which affect gameplay difficulty.
