PEAK Turns a Cheap Co-op Climb Into One of the Funniest Games of the Year

A cheap, chaotic co-op climbing game that turns teamwork into slapstick and sold millions. Thin solo, superb with friends. Verdict: 8.7/10.

The pitch

Overview

PEAK is the kind of game that should not work as well as it does. It is a co-op climbing game, built quickly by a small team, sold for pocket change, about a group of lost nature scouts trying to scale a mountain to escape a mysterious island. There is no epic story, no vast content, no grand ambition beyond one simple, brilliant idea: climbing is hard, falling is funny, and doing both with friends is glorious. Developed by Aggro Crab and Landfall, two indie studios behind games like Going Under and Stick Fight, it launched on 16 June 2025 at a budget price and became one of the surprise hits of the year.

The premise is as lean as it gets. Alone or in a group of up to four, you climb a procedurally shaped mountain, managing stamina, scavenging gear, and trying not to plummet to your doom, because the slightest mistake really can spell the end. That is the whole game, and that is the point. It belongs to the recent wave of cheap, physics-driven co-op games designed to be played with friends over voice chat, where the comedy comes from everyone failing together in creative and humiliating ways.

The reception has been enormous. On Steam the reviews are Overwhelmingly Positive, with roughly 95 percent of a huge number of reviews positive, and the game reportedly sold millions of copies in short order, a wild figure for an indie of this size and price. Players describe it in the language of shared disaster: friends flung off ledges, ropes fumbled, a whole team wiping meters from safety, and everyone laughing about it. It is a word-of-mouth phenomenon in the truest sense.

The honest caveats are about depth and intent. This is a simple, focused game that leans hard on the presence of other people; solo it is far less compelling, and anyone expecting a rich single-player survival experience will find it thin. But judged as what it actually is, a cheap, chaotic, endlessly funny co-op toy, it is close to perfectly designed, and its popularity is entirely earned.

How it plays

Play

At its core PEAK is a physics-driven climbing game, and its genius is how much tension and comedy it wrings from one mechanic. You scale the mountain by grabbing handholds and hauling yourself up, all while a stamina meter drains, and running out at the wrong moment sends you sliding or falling. The mountain is generated so no two climbs are identical, and its hazards, weather, and terrain force you to think about routes, rest, and risk. It is genuinely tense: a long climb can be undone in a second, and that fragility is exactly what makes reaching a ledge feel earned.

With friends, it transforms into something special. Up to four scouts climb together, and the game is built around interdependence: you can rope up, boost each other, share scavenged food and gear, and pull a struggling teammate to safety, or accidentally drag everyone down with you. The best moments come from improvised teamwork and spectacular failure in equal measure, and the physics ensure that helping and hindering look almost identical until the last second. It turns a survival climb into slapstick, and it is consistently, genuinely funny in a way scripted comedy games rarely manage.

Scavenging and light survival systems give the climb texture. You gather items, manage limited resources, and make small decisions about what to carry and when to use it, enough to give each run stakes without ever becoming a heavy management sim. The loop is short, replayable, and easy to drop in and out of, which suits its role as a game you fire up with friends for an hour of chaos rather than a long solo commitment.

The honest friction is depth and solo play. This is a deliberately simple game with a narrow core, and while that focus is a strength in company, alone it exposes the thinness: the climb is still tense, but the comedy and the point both come from other people. Players looking for a deep, content-rich survival game will not find one here, and the experience lives or dies on whether you have a group to play with. It is a party game in survival clothing, and it is best understood that way.

Those caveats aside, it is hard to think of a recent game that delivers so much fun for so little money and effort. PEAK knows exactly what it is, does that one thing extremely well, and asks almost nothing of you but a few friends and a willingness to laugh at your own downfall. As a design exercise in doing more with less, it is close to flawless.

Art & atmosphere

Craft

PEAK's presentation is clean, bright, and built for readability, and that is the right call for a game where a misread ledge means death. The art style is simple and characterful, with expressive little scouts and a mountain whose dangers are clear at a glance, and the whole look prioritizes communication over spectacle. You always understand what is a handhold, what is a hazard, and where your flailing teammates are, which matters enormously when everything can go wrong in an instant.

The design leans into charm rather than grandeur. The scouts are endearing, the animations sell the comedy of a good fall, and the island setting has just enough personality to give the climb a sense of place without distracting from the moment-to-moment tension. It is not trying to be a technical showcase; it is trying to make a mountain that is fun to fall off, and it succeeds.

Sound and physics do the real comedic heavy lifting. The thuds, slides, and yelps of a climb gone wrong, combined with the unpredictable ragdoll of the physics, generate the game's best laughs, and paired with friends on voice chat the audio becomes half the experience. It is a game that sounds funny, and that is a genuine achievement of design. The whole package is modest, polished, and perfectly tuned to its purpose.

A cheap, brilliantly focused co-op climbing game that turns one tense mechanic into endless comedy and became a deserved hit, held back from the top only by deliberate thinness and a heavy reliance on playing with friends.

Pros & cons

The ledger

In its favour

  • One tense, brilliant climbing mechanic that generates endless comedy and drama
  • Superb, interdependent co-op for up to four that turns teamwork into slapstick
  • A procedurally shaped mountain that keeps climbs fresh and unpredictable
  • Extremely cheap for the amount of fun it delivers with friends
  • Clean, readable art and physics tuned perfectly to the comedy
  • A word-of-mouth phenomenon that massively overdelivers on its modest scope

Against it

  • Deliberately simple and thin: far less compelling played solo
  • Lives or dies on having friends to play with
  • Not a deep or content-rich survival game; a focused party experience
  • Little to do once the core loop's novelty settles for some players

    I know a friendslop when I see one. A game subgenre where the lack of strong core mechanics and gameplay loops are replaced with incentives to get a reaction out of you with the cheapest possible tricks on the basis of your friends, not…

    "I like it in here…" - Scoutmaster Myers Peak has finally reached its PEAK. Sad to see this was our final “hey scouts” from the dev but I was glad to be a part of this game's journey to its final major update.

    This game killed itself with the roots update. Who on earth thought that the random clouds of mist that kill would you be a good idea? (I'm not talking about the spores I'm talking about the mist that just straight up comes from no where.)…

Verdict

The call
Playcritik score
8.7/10
Great

PEAK is proof that a great idea, executed with confidence, beats a big budget. Aggro Crab and Landfall took one simple, tense mechanic, climbing a deadly procedural mountain, and built a co-op game so consistently funny and so easy to love that it became a phenomenon on word of mouth alone. It is cheap, it is focused, and it does the one thing it sets out to do about as well as it can be done. For a few euros and a few friends, there is very little that delivers this much joy.

The honest reservations are simply the flip side of that focus. This is a deliberately thin game that depends almost entirely on other people; solo, it loses most of its magic, and anyone hoping for a deep, sprawling survival experience should look elsewhere. It is a party game wearing survival clothes, and it should be judged as one.

But judged that way, it is a small triumph. If you have a group and a spare hour, PEAK will give you some of the funniest, most memorable gaming moments of the year for almost no money, and it will do it again and again. It is not deep, and it does not need to be. As a cheap, chaotic, joyfully designed co-op climb, it is an easy and enthusiastic recommendation, one of the best-value games you can buy.
