Moving on the fells
- Jump higher by holding the button. You can still jump just after running off an edge, and a press just before landing is remembered.
- Wall jump by pressing jump next to a crag.
- Climb by holding grab against a crag. Climbing uses stamina, which refills when you stand on the ground. A sweat drop means your arms are nearly done.
- Dash in any of eight directions. Your buff turns orange when a dash is ready and blue once it's spent. Touch the ground to recharge.
- Kendal mint cake refills your dash and stamina in mid-air. On Scafell Pike, some gaps can only be crossed by dashing to a mint cake and dashing again.
- Loose rock (blocky brown slate) cracks, with a sharp click, as soon as you stand on it or grab it, and falls away a moment later. Keep moving. It settles back after a couple of seconds.
- Cairns are checkpoints. Sharp rocks, tarns and big drops send you back to the last one.
- Signposts on the way up Blencathra explain each move as you pass them. You can turn the tips off in Settings.
Weather
- Wind pushes you around, especially in the air. It's gentler down in the valley and full strength on the tops. Watch the wind gauge, streaks and your buff. The gust warning gives about a second's notice.
- Shelter: crags, boulders and walls on the windward side break the wind. The gauge says Sheltered when you're in their lee.
- Rain and snow make the rock greasy: you'll slide further when stopping or turning.
- Clag (hill fog) hides the way ahead. You can limit it in Settings.
Speedrunning
- Every run's weather comes from its seed. The same seed gives the same gusts at the same moments, so share one with friends for a fair race.
- Each fell has target times: gold for a skilled runner's pace, then silver and bronze. They're the same in every weather, so a storm makes them harder.
- Your fastest run on each fell and weather setting is saved with a ghost to race. Splits at each cairn show whether you're ahead, and the route map at the bottom of the screen shows you (●) and your ghost (○).
- Watch best run replays your ghost in the weather it ran in. You can also watch any run again from the results screen.
- Super jump: jump during a sideways dash on the ground. Hyper: dash down-diagonally into the ground, then jump. Wall bounce: dash upwards beside a crag, then jump.
Real fells & mountain rescue
Sharp Edge, Striding Edge and the Scafell massif are real places, and real people are hurt on them every year, often in exactly the weather this game throws at you. On the real fells there are no respawns.
- Check a mountain forecast before you go, such as the Lake District Weatherline (opens in a new tab) or MWIS (opens in a new tab).
- Carry a map and compass and know how to use them, plus warm layers, a waterproof, a torch and food.
- Turning back is always an option.
In an emergency in the UK mountains, dial 999, ask for the Police, then Mountain Rescue.
Lakeland's mountain rescue teams are unpaid volunteers, on call around the clock, every day of the year, and funded mostly by donations. If you enjoy the fells, in real life or in pixels, please consider supporting them.
