About the Game
REALISTIC CLIMBING SIMULATION
Cairn’s realistic simulation allows intuitive climbing: find the best holds and place your hands and feet seamlessly with simple controls. Adapt your posture, effort and balance —if you're not careful, you will fall!
THE ASCENT OF A LIFETIME
As pro climber Aava, you embark on the ascent of Mount Kami, a summit that has never been reached. Along the journey, meet unexpected companions and hear from those left on the ground. Discover the mountain's history and decide what Aava is willing to sacrifice to achieve her dream.
OPEN YOUR OWN ROUTE
You are free to climb anywhere. Explore the mountain, read the rock face from the ground and plan your route carefully to reach the top. Solve problems while on the wall to navigate difficult sections. You can climb on anything, so choose your path wisely!
CLIMBING IS A FIGHT
Climbing is challenging: each wall feels like a boss fight. A thrilling challenge for those eager to test themselves, but you can also adjust the difficulty to customise your experience.
SURVIVE THE DEADLY MOUNTAIN
Manage your resources to survive during the long ascent: pitons, chalk, finger tape... but also food, water and medicine. Set up bivouacs and explore the mountain to find resources to reach the summit.
AWARD-WINNING INDIE TEAM
An unforgettable experience from the makers of Furi and Haven, with music and sound design by the team behind Limbo, Inside, Control and Cocoon, and art and story by renowned comic-book artist Mathieu Bablet.
