Cairn - Systems
The systems that drive Cairn's climb. Everything is built around the same idea: the mountain is solved with the body first and the inventory second.

| Name | Type | Description | Abilities | Source |
|---|---|---|---|---|
| Limb-Based Climbing | Core System | The simulation at the centre of Cairn. The player places Aava's hands and feet one at a time, choosing which hold each limb takes instead of holding a climb button, so progress depends on reading the rock and finding a sequence that the body can actually hold. | Independent hand placement Independent foot placement Hold reading on natural rock | Core climbing system |
| Posture and Weight Distribution | Core System | Each hold shifts Aava's balance and reach, and the game tracks her posture as she moves. | Body position tracking Balance and reach limits Audible exertion feedback | Core climbing system |
| Grip and Chalk | Survival System | Grip is the resource that decides whether Aava stays on the wall. | Depleting grip meter Chalk restores grip Chalk bag capacity upgrades | Core survival loop |
| Pitons and Checkpoints | Core System | Pitons are both protection and the game's checkpoint system. | Fall protection Checkpoint on placement Limited piton supply Unbreakable troglodyte pitons | Core climbing and save system |
| Hunger, Thirst and Stamina | Survival System | Cairn tracks hunger and thirst alongside physical fatigue, and supplies have to be scavenged and foraged during the ascent rather than bought in bulk beforehand. | Hunger meter Thirst meter Stamina and fatigue Foraging and cooking | Survival layer |
| Weather and Day-Night Cycle | World System | Weather and the time of day change the difficulty of each climb, from what the player can see to how the rock and ice behave. | Dynamic weather Day and night cycle Visibility changes | World simulation |
| Backpack and Resting at Pitons | Inventory System | Supplies live in a backpack with limited space, and the backpack is opened when Aava is off belay at a piton. | Limited inventory slots Access backpack at a piton Eat, drink and refill chalk at rest | Inventory layer |
| Route Planning on a Vertical Open World | Traversal System | Mount Kami is a connected vertical open world rather than a set of levels. | Free climbing lines Optional detours and hidden areas Connected areas instead of levels | World structure |
| Expedition Mode | Game Mode | A separate mode outside the story campaign. | Aava or Marco as avatar Climbing style selection Route selection | Additional game mode |
| Lore Notes and Optional Discoveries | Collectible System | Notes, monuments, hidden rooms and leftover tourist infrastructure carry the mountain's history. | Collectible notes Hidden rooms and monuments Environmental storytelling | Exploration layer |
