PEAK: Complete Guide

Everything you need to go from a first Tenderfoot climb to clearing Ascent 8: stamina and afflictions, every biome, the items worth carrying, and how the Ascent ladder works after The Final Ascent update.

Researched September 2026 — current as of patch 2.4.c (post "The Final Ascent" v2.0.a). Live games change; check the linked sources if something differs.

Quick Start

  1. Stamina is everything. One bar handles climbing, sprinting and jumping, and every affliction (hunger, injury, cold, poison...) eats into that bar's maximum. Keeping afflictions low is how you keep climbing.
  2. Stop and rest on ledges. Stamina only regenerates when you're standing on solid ground. Never start a long wall with a half-empty bar.
  3. Open every piece of luggage you pass early on. Suitcases and luggage are where most food, rope and healing items come from.
  4. Eat before hunger gets big. Hunger grows slowly but never stops. Snack on berries and packaged food as you go instead of starving and then panic-eating.
  5. Use your teammates. Right-click gives a helping hand to pull a scout up a ledge, and players can boost each other on climbs. Four scouts working together climb much faster than four solo climbers.
  6. Learn which berries are safe. Berry colors and types change between runs, so some can poison you or cause spores. Let one person test unknown food, or cook it at a campfire first.
  7. Light every campfire. Campfires split the climb into sections. They heal some injury, let you cook, and mark real progress.
  8. Carry rope. Rope Spools, Rope Cannons, Pitons and Chain Launchers get you past walls you can't free-climb.
  9. Bring a flare to the summit. You win by reaching the Peak and firing a flare for the rescue helicopter. From Ascent 4 on there's no flare waiting at the top, so you have to carry your own.
  10. Start on Tenderfoot. It's the easy mode (less climbing stamina drain, slower hunger). Clearing it unlocks normal Peak difficulty.

What PEAK Is

PEAK is a co-op climbing game for 1-4 players from Aggro Crab and Landfall Games. It came out on Steam on June 16, 2025. You play lost Scouts climbing a procedurally generated mountain island. The map changes daily, and a run is one climb from the beach to the summit.

The Final Ascent (v2.0.a, August 11, 2026) is the last major content update. It added the Gloom and Citadel biomes, Ascent 8, the Jetpack, Glider and Warp Fungus, Clown Luggage, 10 new badges and a secret Scoutmaster storyline. Later patches (2.01-2.4.c) balanced frogs and infinite-stamina effects, brought Caldera and The Kiln back into rotation, and added room codes to prepare for cross-platform play. The devs have confirmed console ports with crossplay.

The Stamina Bar and Afflictions

Your stamina bar holds 100 points. It drains when you climb, sprint (about 5/sec), jump (5) or sprint-jump (15). Once you've been on the ground for a moment, it regenerates quickly. Afflictions stack onto the bar as colored segments and lower your usable maximum. Bonus Stamina (the extra bar from food like Energy Drinks and Granola) gets spent only after normal stamina runs out. It doesn't regenerate.

Affliction Main causes How to remove it
Hunger Builds constantly over time Any food, Cure-All
Injury Falls, lava, explosions, zombie bites, antlions Bandages, First Aid Kit, campfire, some berries, Cure-All
Poison Bad food, urchins, jellyfish, spiders, stings, ticks Antidote, Medicinal Root, Remedy Fungus, First Aid Kit (it also wears off slowly)
Spores Shroomberries, spore clouds, zombies Antidote, Medicinal Root, Remedy Fungus
Cold Alpine blizzards, fog, cold nights (Ascent 5+) Huddle with teammates, Lantern, Heat Pack, campfire, hot springs, Portable Stove
Heat Mesa sun, hot rocks, lava, Scorchberries Sports/Energy Drink, Aloe Vera, Half-Coconut, Winterberries, shade/pools (it decays out of the heat)
Drowsy Blowgun darts, Napberries, Mandrake, Gloom fog Energy Drink, Cure-All (it also decays)
Thorns Cacti, tumbleweeds, Prickleberries Pull them out manually; they also drop off over time
Curse Statue revivals, Book of Bones, Ascent 7-8 Cure-All, Pandora's Lunchbox, cooked Mandrake. It never decays on its own
Weight Everything you carry Drop or use items

Key numbers from the wiki:

Biomes, in Order

A run goes through these segments in order. Campfires separate them.

Segment Variants What to watch for
1. The Shore Shore Easy start. Loot the crash-site luggage, and watch out for urchins and jellyfish on the beach.
2. Tropics / Roots Tropics or Roots Tropics has poison plants, spiders and lots of fruit. Roots (added Nov 2025, rebalanced in 2.0) has beetles, spore mushrooms and giant roots.
3. Alpine / Mesa Alpine or Mesa Alpine brings cold, blizzards and ice. Mesa (added Aug 2025) brings heat, cacti, scorpions and tumbleweeds, but its pools cool you down.
4. Volcanic / Gloom Caldera + The Kiln or Gloom + The Citadel Caldera has lava, hot rocks and condors, and The Kiln is the interior climb. Gloom has drowsy fog and belltowers. The Citadel has arrow traps and wrought-iron fences.
5. The Peak Summit Fire the flare. On Ascent 8 you must instead bring all the amulets to the statue to unlock the escape.

The map rotates on a schedule, so everyone in the world climbs the same layout on a given day. If you get stuck on a route, try again tomorrow or learn the day's line.

Items Worth Knowing

Climbing and movement

Healing and cleansing

Food: Granola Bars, Scout Cookies, Trail Mix and berries (Crispberries, Winterberries, Kingberries and more). Packaged food is safe. Unknown berries can be a gamble.

Special items

Your backpack adds extra storage (slot 4), but everything you carry adds Weight. Weight takes up bar space the same way afflictions do. Share the load across the team.

Death and Revival

When a scout goes down, other players can carry the body. Ancient Statues (altars on the mountain) revive dead scouts, but the revived scout gains Curse, and on Ascent 7+ that Curse cost goes up. Because Curse never decays, every revive permanently lowers your team's stamina ceiling until someone uses a Cure-All or Pandora's Lunchbox. Don't count on revives in the late biomes.

The Ascent Ladder

Each clear unlocks the next difficulty. Modifiers stack, and each level includes all previous ones. Only one player in the group needs the Ascent unlocked. Clears reward Scout Sashes (Tadpole for Peak, up to the Scoutmaster Sash for Ascent 8; Ascent 7 also gives Goat Horns).

Level Added modifier
Tenderfoot Easy mode: climbing costs 30% less stamina, hunger grows 30% slower, no fog or zombies
Peak Normal difficulty: fog and zombies, and Scoutmaster Myres can appear
Ascent 1 Fall damage is doubled
Ascent 2 Hunger grows 60% faster
Ascent 3 Every item weighs more (+2.5 weight each)
Ascent 4 No flare at the summit, so bring your own
Ascent 5 Nights are cold (roughly 100 cold over a night)
Ascent 6 Climbing costs 40% more stamina
Ascent 7 Start with 10 Curse, and each revive adds +15
Ascent 8 Final challenge: collect all the amulets and place them on the statue to open the escape

FAQ

How many players can play PEAK? 1-4. It's designed around 4.

Is PEAK cross-platform? It isn't yet, as of September 2026. Room codes were added in 2.04.a to prepare for it, and console versions with crossplay have been announced.

Is The Final Ascent the last update? Yes. The devs called v2.0.a the final major content update. Bug-fix patches (up to 2.4.c on September 14, 2026) have continued.

Why is my stamina bar short even at full? Afflictions and Weight fill part of the bar. Eat, heal, warm up or drop items to get the space back.

How do I unlock Ascents? Clear the summit on the previous difficulty. Only one player in the group needs the unlock.

How do I revive a dead friend? Carry them to an Ancient Statue. The revive adds Curse, and on Ascent 7+ it adds more.

Why can't I find Caldera or Gloom? The fourth segment rotates. Some days it's Caldera + The Kiln, other days it's Gloom + The Citadel.
