Cairn – meet the cast!

Hello climbers,

Cairn is featured in the Tribeca Festival! Tribeca is famous for its independent films and games selection, which made it a great opportunity for us to tell you more about Cairn’s story and the people who bring it to life. Indeed Cairn is not just a fantastic sandbox for climbing in realistic conditions, it also follows the deep and emotional story of Aava, attempting to ascent a mountain she trained for her whole life.

We’ve mentioned it before, Cairn’s art director and writer is Mathieu Bablet, the acclaimed author of award winning comic books Carbone & Silicium or Shangri-la. Renowned for his thought-provoking storytelling and visually stunning science fiction, Bablet brings his signature depth to Cairn. He crafts a gripping journey centered on Aava: her will to push herself beyond the limits—but also about the encounters she makes along the way, and the sacrifices she must face to accomplish her dream.

Aava is a tough and experienced climber, on her way to be the first to reach the summit of Mount Kami. Multi-award winning actress Sophia Eleni (Assassin’s Creed Mirage, Call the Midwife, Dungeons and Dragons…) is giving Aava all her determination and grit.

Actress and singer Camille Constantin Da Silva & Gildaa also contributes to bringing Aava to life by giving her her singing voice but also by conveying the character’s intense efforts with a rich mosaic of breath, strain, and pain sounds.

Along the ascent, Aava will meet Marco. A polar opposite of Aava, he’s cheerful and social. Hyoie O’Grady (The Division 2, Outlander…) conveys the young climber’s aspiration and his humanity.

Chris is Aava’s agent. His star climber is about to embark on the most difficult ascent in the world, and become a legend. But Adam Howden (Final Fantasy XIV, Metaphor Re:Fantasio, Xenoblade Chronicles…) is not exactly living the dream — chasing her for updates to keep the sponsors from having a meltdown. 

With over 15h of playtime for the main storyline only, Aava will make unexpected encounters along her ascent and meet characters yet to be revealed, played by an excellent cast:
Aaron Neil (Peaky Blinders, Jurassic World Evolution 2, Castlevania: Nocturne…
Rebecca Benson (Game of Thrones, Doctor Who, Xenoblade Chronicles 3…)
Alexandra Boulton (Dragon Quest…)
Rich Keeble (Clair Obscur: Expedition 33, Split Fiction, New World: Aeternum…) 

The voice actors were directed by SIDE UK’s team of amazing voice directors: Kate Saxton and Damien Goodwin. 

Cairn – in-depth gameplay presentation

We’re happy to confirm that survival-climber Cairn will release on PS5 November, 5 2025. You can attempt your first ascent with Aava today, as a demo is available now on PS5! Go and hone your climbing skills on the Tenzen mountain ridge before the ascent of unforgiving Mount Kami.

It’s not the mountain we conquer, but ourselves

A cairn is a stack of stones piled up to mark a trail or as a memorial. It’s a very good representation of the idea “I made it this far”.

In Cairn, our survival climbing game, you will need determination and persistence to “make it this far”. When we decided to make a video game about alpinism, we were fascinated by the dedication and resolve shown by climbers. They are ready to risk everything because of how extraordinary it makes them feel: extremely satisfied and free. And that’s the emotion we wanted to replicate and make you feel, as a player. 

We spent 3 years of research and development to create our own way to climb. It’s completely unique and new. You’ve climbed already in video games, but most games use climbing as a traversal mechanic, to reach a different location. In Cairn, climbing is the actual challenge, it’s where you fail or succeed. It’s what will make your hands sweat. 

The pillars of our climbing gameplay are what make it unique: a simple yet deep climbing control, and total freedom to climb anywhere.

Easy to learn, hard to ma…ouch! my finger!

First, it is simple to climb. We made a deep simulation gameplay while keeping simple inputs. In Cairn you control each hand and feet individually, but with just the left stick and one button to grab the wall. Ninety percent of the inputs you make are just moving the left stick and pressing Square. Feels simple right? So does Gran Turismo when you steer and accelerate with the same two inputs, but yet you’ll be practicing for hours to improve your lap time by 3 seconds. In Cairn the challenge is not about the controls of the limbs, it’s about placing them tactically, and keeping your character in balance. 

We worked on an advanced movement system that makes your character move like a climber according to what you aim for with your hand or foot. The simulation calculates the body mechanic, but also the efforts, and your character gets tired and out of breath in consequence.  

The result is a very strong immersion: you only look at your character, listen to their breathing, feel their limbs shaking directly on your hands with the precise Dualsense controller vibrations. There is no UI feedback. You learn to read the exhaustion status of the climber. By practicing, you know what’s an impossible move, a bold one and a safe one. 

What’s great with climbing is that the goal is pretty clear: reach the next ledge, the next summit. You see your objective, you just have to reach it. And failing is pretty obvious too: you fall. This helps you focus on what’s important: your body, your movements, your stamina. And eventually, when you reach that ledge, relief and joy!

Route-finding is speaking the mountain’s language

The second revolution in Cairn is the freedom to climb everywhere. It’s not a path or a branching of paths designed by level designers, it’s a whole mountain and you can slip your hand into every crack you see. 

The mountain was built rock by rock by our design team (whom I thank dearly). And that brings incomparable feelings of freedom. Even our level designers don’t know where you’ll climb, what route you will choose. 

During our playtests, we noticed something quite interesting: video game players usually walked towards the wall and started climbing. While actual rock climbers looked at the wall before climbing, noticed cracks, holds, hoverhangs, jugs in the rock, and decided on a route. Planning ahead, adapting to the wall, pausing to breathe and rest, decrypting the rock… it’s part of the fun in Cairn. Every second you play, you’re facing a choice. 


Topping out

Cairn is not only a climbing simulation. It’s an immersion into a beautifully stylized nature, it’s hearing a storm rumbling, alone in the mountain, it’s surviving hunger, cold, thirst and pain. It’s about Aava’s journey as she attempts to reach the summit, and the people and places she will find on the way. It’s about her determination and sacrifices, her search for freedom. But we’ll let you know more about all these aspects of the game soon…
