The best four-player game of its generation. Still Windows-only, and that decides whether you can buy it.
Short verdict: if all four of you are on PC, buy it - PEAK is the clearest, funniest, cheapest co-op experience released in the last two years, and the ten million people who bought it in its first two months were not wrong. If anyone in your group is on PS5, Xbox or Switch, you cannot buy this game for them, and no date exists for when you can. As of October 6, 2026 PEAK is Windows via Steam only. Console versions are confirmed in development with full crossplay promised, but the developers have given no timeframe. Skip to the alternatives below if that is your situation - Content Warning is the honest substitute and it is on every current console.
PEAK is a four-player co-op climbing game from Aggro Crab and Landfall Games, released on June 16, 2025. You and up to three friends start at the bottom of an island mountain and try to reach the top. There is no combat, no enemy and no story. The entire game is terrain, stamina, a handful of items and three other people who are also bad at this.
What you actually do
Each run is one mountain, generated fresh - the official description is explicit that the terrain regenerates daily, so the route your group failed yesterday is gone. You climb through four biomes toward the summit. Climbing drains stamina, and stamina is the whole resource economy: it recovers when you stand on solid ground, it does not recover mid-wall, and running out while hanging means falling. Injuries, hunger and status effects stack on top of that and are cured with items you find or carry up.
Two mechanics turn that into a group game rather than four solo climbs. The first is rope: anyone can place it, everyone can use it, and a well-placed anchor is the difference between a group summiting and a group restarting. The second is proximity voice chat, which means distance is audible - someone who falls two screens down genuinely goes quiet, and the panic of finding them is the game's best recurring joke.
The result is a game where the interesting decisions are social. Do you spend your one bandage on the person who is about to attempt the hard route, or keep it? Does the group wait for the slow climber at the ledge, or push on and leave them a rope? None of that is written anywhere in the game. It emerges because the stamina economy is tight enough that generosity actually costs you something.
How it was made, and why that matters to the review
PEAK was built in a one-month game jam in February 2025 - a collaboration between two existing studios, Aggro Crab and Landfall, described by one of the developers as "fun, fast and wild cowboy development". It is relevant to a buying decision for two reasons.
The good reason: the scope is honest. Nothing in PEAK is padded, because there was no time to pad it. You get one excellent idea executed cleanly for a price that reflects that, rather than a thin idea stretched to justify sixty dollars.
The less good reason: a game-jam codebase is why the console versions are slow. When fans pushed for a port, the developers' public answer was essentially that porting games takes a while and a game jam build takes longer - with no timeframe attached. Treat any console date you see online as a rumor until Aggro Crab or Landfall announce one.
The numbers, and what they are worth
PEAK sold more than 100,000 copies in its first 24 hours, a million in under a week, two million in nine days, five million in its first month and over ten million by mid-August 2025. On reviews it holds a Metacritic score of 82, and it took a 9 out of 10 from Game Informer and 86 from PC Gamer.
Sales figures that large tell you something real about this specific genre: friendslop spreads by one person buying it and then three friends having to. A ten-million-copy game at this price point is roughly 2.5 million groups, which is a better signal than any review score that the thing works as advertised with a normal group of friends.
The game also kept shipping after launch rather than cashing out - the Mesa biome arrived in August 2025, Roots in November 2025, and a final major update called The Final Ascent added the Gloom and Citadel biomes in August 2026. If you bought it at launch you now own roughly twice the mountain you paid for.
Who should not buy it
Anyone without three available friends. PEAK supports solo play and it is close to pointless that way. The mechanics - rope, item sharing, proximity chat, the social cost of waiting - only produce anything with other people in the call. This is the defining limitation of the whole friendslop genre, and PEAK is the purest example of it.
Groups that want a campaign. There is no story, no progression that carries between runs in the way an RPG means it, and no ending beyond reaching the summit. Groups who want narrative structure and a credits roll should be looking at co-op campaign games instead.
Anyone who cannot use voice chat. Proximity chat is not a convenience here, it is a mechanic, and PEAK loses most of its value played silently. If voice is off the table for your group, games that work without voice chat is the right list.
Anyone easily motion-sick. First-person climbing with physics-driven falls is close to a worst case for motion sensitivity. Steam lists Camera Comfort features, but go in knowing that.
