Climbing and Survival Mechanics
PEAK runs on two resources: stamina and hunger. Every action you take ties back to one or both of them. The climbing system is physics-based, the survival loop is unforgiving, and your item choices determine whether you reach the next campfire or slide back down to the last one. Once you understand how each system works, the mountain becomes a problem you can solve instead of a wall you throw yourself against.
Stamina System
Stamina is a continuous bar that drains during physical activity and refills while standing on flat ground. When it hits zero, you lose your grip on whatever you are holding and fall.
Actions that drain stamina:
| Action | Drain Rate | Notes |
|---|---|---|
| Hanging on a wall (stationary) | Low | You drain stamina just by holding on, even without moving. |
| Climbing (moving while grabbed) | Medium | Standard drain. Faster movement means faster drain. |
| Jumping/Leaping | High (burst) | Each jump eats a fixed chunk. The distance gained is proportional to stamina spent. |
| Sprinting | High (continuous) | Only possible on flat ground. Useful for crossing horizontal gaps. |
| Dashing | Medium (burst) | A short burst of speed. Can be used mid-air for repositioning. |
Stamina recovery:
- Stand on any flat surface. Recovery starts after about one second of standing still.
- Recovery speed is constant. You cannot speed it up with items or abilities.
- Pitons create artificial flat surfaces on walls. Hammer one in, stand on it, and recover mid-climb.
Stamina and Hunger Interaction
Hunger directly shrinks your maximum stamina. As your hunger bar fills, the right side of your stamina bar grays out. At full hunger, your maximum stamina drops to roughly 30% of its base value. That is enough for about two wall grabs before you fall.
The relationship is linear. Half hunger equals roughly 65% max stamina. Keep hunger below the halfway mark and your stamina bar stays large enough for sustained climbing.
Hunger fills over time regardless of what you are doing. Standing still, climbing, falling. The meter always ticks up. You need to eat regularly, not just when you feel low.
Advanced Stamina Techniques
Dash-jump conservation. When your stamina bar is nearly empty, a well-timed dash-jump covers distance without the full jump stamina cost. Press dash immediately before jumping. The dash animation cancels into the jump, and the combined cost is less than doing them separately.
Piton chaining. On long vertical sections, place pitons every 15 to 20 meters. Climb to a piton, rest until full, climb to the next one. This turns an impossible wall into a series of short, manageable sections.
Leap timing. Leaping from a wall propels you further when your stamina is above 50%. Below 50%, the leap distance drops. Always leap while you still have gas, not as a desperation move when your bar is empty.
Rest ledge identification. Flat surfaces with a green tint are always safe rest spots. Some surfaces look flat but are angled enough to slide off. If the tint is not green, test it carefully before committing.
Hunger and Food
Hunger is a survival timer. It fills slowly over time and shrinks your maximum stamina as it grows. Managing hunger is about eating the right food at the right time.
Food Sources
| Food Type | Where to Find It | Hunger Reduction | Notes |
|---|---|---|---|
| Coconut | Shore, Tropics trees | High | Crack open for two uses. Best early-game food. |
| Berries | Bushes in all biomes | Low to Medium | Some are poisonous. Color indicates safety (learn the types per daily map). |
| Mushrooms | Shaded areas, caves | Medium | Most are safe. A few cause status effects. |
| Honeycomb | Tree nests | High | Rare find but very effective. |
| Fish | Shore waters, streams | Medium | Must be cooked to be effective. Raw fish gives minimal hunger reduction. |
| Packaged Snacks | Luggage, wreckage | Medium | Reliable and safe. No cooking needed, but cooking improves them. |
Cooking Rules
Cooking transforms food at campfires, portable stoves, or any heat source (including dynamite explosions and Caldera geysers). The system has four stages:
- Raw. The item's base stats. Eating raw food works, but you miss significant bonuses.
- Cooked (first cook). Doubles the hunger reduction value. Multiplies existing bonus stamina by 1.5x, with a guaranteed minimum of +10 bonus stamina even if the raw item provided zero. Always do this.
- Well-done (second cook). Identical to Cooked. The same doubled hunger and 1.5x stamina bonus. Acts as a safety buffer. You do not lose anything by cooking twice.
- Incinerated (third cook and beyond). Destroyed. Eating incinerated food inflicts 4 Poison per incineration, stacking up to a maximum of 36 Poison.
Cook everything at least once. The doubled hunger reduction and +1.5x stamina bonus from cooking is the strongest buff in the game. If you accidentally cook twice, do not panic. Well-done is identical to Cooked. Just do not hit it a third time.
Cooking exceptions:
- Cooking neutralizes most poison, thorns, and spore debuffs from toxic berries. A few mushroom variants (bugle, button, and cluster) are exceptions and stay toxic after cooking.
- Certain packaged items (Airline Food, Trail Mix, Granola Bars) do not benefit from the hunger multiplier when cooked. They still receive the stamina bonus.
- Non-food items (rope, pitons, gear) should not be cooked. Placing them on a campfire destroys them.
- The Big Lollipop gives a massive temporary stamina boost but causes drowsiness afterward (reduced movement speed for about 30 seconds). Cook it once for a stronger initial boost, but the drowsiness duration stays the same.
You are not limited to campfires for cooking. Portable stoves, dynamite explosions, and even natural heat from Caldera geysers can instantly cook items in emergencies. If your team is starving mid-climb and no campfire is nearby, get creative with heat sources.
Status Effects
Environmental hazards and certain items inflict status effects that limit your capabilities.
| Effect | Cause | Impact | Cure |
|---|---|---|---|
| Poison | Toxic berries, sea urchins, jellyfish, incinerated food | Drains health over time | Cure-All, Antidote, or Medicinal Roots |
| Frostbite | Alpine cold, blizzards | Slowly reduces your maximum stamina capacity over time | Lantern, Portable Stove, Heat Pack, or campfire |
| Burn | Caldera lava surfaces, fire hazards | Deals damage on contact and briefly after | Bandage for health, move away from heat |
| Slippery | Rain in Tropics, ice in Alpine | Reduced grip on surfaces, easier to slide off | Wait for weather to pass, or use pitons for anchor points |
| Drowsiness | Big Lollipop aftereffect | Reduced movement speed | Wait it out (about 30 seconds) |
| Sunburn | Mesa sun exposure | Gradual health drain while exposed | Find shade, Aloe Vera, or use a parasol |
| Spore | Roots biome fungi and infectious zombies | Builds up over time. High Spore toxicity causes hallucinations and eventual death | Cure-All, or avoid prolonged fungal exposure |
Frostbite is the most dangerous status effect for climbers. It does not increase your active stamina drain rate. Instead, it slowly shrinks your maximum stamina capacity over time, suffocating your reserves until you pass out. Carrying a Lantern, deploying a Portable Stove, or consuming Heat Packs actively restores lost capacity. Simply resting is not enough.
Tools and Gear
Your inventory has limited slots. Choosing the right loadout before a climb section determines how far you get.
Traversal Tools
Rope Spool. Place rope anchored to a surface. The rope extends downward (or in the direction of gravity) and other players can climb it without spending stamina. The single most valuable co-op tool. Solo players benefit too since rope lets you retreat safely if a path does not work out.
Piton. Hammer into any wall surface to create a small standing platform. Stand on it to recover stamina. Place them at intervals on long climbs. Each piton is single use, so carry several.
Chain Cannon. Fires a projectile that anchors to a distant surface and creates a swingable chain between the firing point and the anchor. Covers horizontal and vertical gaps that are too far for a jump. Aim carefully because the chain has a fixed length.
Magic Bean. Plant on a horizontal surface to grow a tall beanstalk. The stalk is climbable and covers significant vertical distance in one shot. Rare item but invaluable when you find one. Single use.
Healing Items
Bandage. Restores a portion of health. Use on yourself or hold near a teammate to apply to them. Basic healing for fall damage and hazard exposure.
First Aid Kit. Stronger healing than a bandage. Restores more health per use. Less common but worth carrying for dangerous biomes.
Cure-All. Removes all active negative status effects (poison, burn, frost). Does not restore health. Carry one in the Alpine and Caldera biomes as insurance.
Utility Items
Lantern. Emits light and warmth. Counteracts the Frost status effect in Alpine zones. Also reveals hidden paths in dark cave sections. Stays active in your inventory without needing to hold it.
Flare. Temporary light and heat. Shorter duration than a lantern but can be thrown to illuminate distant areas. Also scares off some environmental hazards.
Compass. Points toward the next campfire when held. Useful on daily maps where the path is not obvious. Does not show the route, just the direction.
Binoculars. Zoom in on distant terrain while standing still. Spot luggage, hazards, and rest spots before committing to a climb. Free to use, no charges or durability.
Bugle of Friendship. Play it to grant infinite stamina to all nearby players for 10 seconds. The most powerful co-op tool in the game. Time it for a difficult climb section and your entire team can sprint up a wall without worrying about grip failure.
The Bugle of Friendship also works solo. The infinite stamina applies to you as well. Save it for the hardest vertical section in each biome and use it when your stamina bar would otherwise run out mid-climb.
Inventory Management
You can carry a limited number of items. The exact slot count varies depending on your scout's equipped backpack (cosmetic variations do not change capacity). Managing your loadout is a constant decision.
General priorities by biome:
| Biome | Must-Have | Nice to Have | Skip |
|---|---|---|---|
| Shore | Food (coconuts) | Rope, Piton | Lantern (not needed yet) |
| Tropics | Food, Cure-All | Piton, Compass | Lantern (still warm) |
| Alpine | Lantern, Food, Piton | Cure-All, Rope | Chain Cannon (terrain is vertical, not horizontal) |
| Caldera | Food, Bandage, Cure-All | Chain Cannon | Lantern (too hot) |
| The Kiln | Food, Food, Piton | Bandage | Everything else (speed matters most) |
Drop and swap. You can drop items on the ground. If your inventory is full and you find something better, drop the least useful item. In co-op, drop items near teammates who need them more.
Advanced Climbing Techniques
These techniques separate first-time climbers from summit veterans:
Wall jumping. Jump off a wall at an angle to reach an adjacent surface. Costs stamina but covers gaps between two climbable surfaces that are not connected. The key is pressing jump while angled toward your target, not straight up.
Momentum swinging. While hanging from a chain (Chain Cannon) or rope, swing back and forth to build momentum. Release at the peak of the swing to launch toward a distant ledge. The timing is physics-based and takes practice.
Piton laddering. On completely featureless vertical surfaces, place pitons in a staggered pattern (left, right, left, right). Each piton gives you a rest point and a launch point for the next grab. Expensive in piton count but lets you climb anything.
Teammate boosting. In co-op, one player hangs on the wall and the other grabs them, then climbs over them. The bottom player acts as a human handhold. Coordinates well over proximity chat.
Last-second leap. When your stamina bar hits zero, you have a split-second window to press jump. The leap uses your last bit of energy for one final launch. The distance is short, but it can be enough to reach a ledge you would otherwise miss. Practice the timing on the Shore before relying on it in the Alpine.
Rope Storage (advanced exploit). Start a rope anchor placement at the peak of a jump, then fall back down while the animation completes. The anchor places itself at the apex of your jump height, far higher than a grounded placement would allow. The developers patched this out initially but restored it in Patch 1.48.a after community petition. It is now considered legitimate movement tech and is practically mandatory for solo Lone Wolf runs and high-level speedruns.
Advanced techniques are not required to reach the summit on the default difficulty. They become necessary on higher Ascent tiers where stamina drains faster and rest spots are rarer.
