ESRB Rates PEAK for PlayStation 5, Naming Skybound Games

The Entertainment Software Rating Board has rated PEAK, the co-op climbing game made by Aggro Crab and Landfall, for PlayStation 5. The ESRB’s listing assigns the game an E10+ for Everyone 10+ rating with a Fantasy Violence content descriptor and a Users Interact interactive element, and it names Skybound Games on the entry. The game released on PC in June 2025.

PEAK currently appears among the most-viewed game ratings on the ESRB’s homepage, listed alongside Grand Theft Auto VI, Grand Theft Auto V, and Cyberpunk 2077. The listing does not state a release date, and the developers’ official announcements have so far discussed console ports without naming a platform.

What the ESRB Rating Summary Describes

According to the board’s rating summary, PEAK is a co-op adventure game in which players control a character stranded on a mysterious island. From a first-person perspective, players work with other players to climb mountains, collect tools and items, and help each other survive.

The summary describes various obstacles rendered in highly stylized graphics: spiders that bind characters, and zombies that attack players by grabbing and slamming them to the ground. When players’ hunger levels run too low, the summary states, they can eat other characters, which appear as rotisserie chicken and produce cartoony skeleton effects.

The ESRB’s rating system has three parts: rating categories that suggest age appropriateness, content descriptors that indicate content that may have triggered a rating, and interactive elements. Per the board’s ratings guide, interactive elements highlight online features such as players’ ability to interact with each other and do not influence a product’s rating assignment.

The Game and Its Makers

PEAK released on Steam on June 16, 2025, priced at $7.99. The store page lists Team PEAK as developer and Aggro Crab as publisher. Aggro Crab describes the title as a co-op survival climbing game made in collaboration with Landfall Games, while Landfall credits the game as made together with Aggro Crab.

In the game, a group of lost nature scouts stranded on a mysterious island must scale the mountain at its center to have any hope of rescue, either solo or in friends-only online co-op with up to three other invited scouts. Players communicate through proximity chat and climb through four biomes, each with its own life-threatening obstacles, on a mountain map that rotates every 24 hours. Every setback limits a scout’s stamina and makes climbing harder, so players scavenge for food and survival items ranging from energy drinks to climbing spikes to what the store description calls the mysterious Anti-Rope. The page also lists dozens of earnable badges and unlockable cosmetics, character customization, campfires and marshmallows, and ghosts, with offline single player available alongside online co-op.

Steam lists PEAK as Overwhelmingly Positive, with 95% of its 146,571 English-language user reviews positive, while reviews from the last 30 days are Very Positive at 93% of 7,234. The store page also records the game as winner of the Better With Friends Award at The Steam Awards 2025.

Aggro Crab’s catalogue also includes the soulslike adventure Another Crab’s Treasure, set in a crumbling underwater world, and Crashout Crew, an online co-op game in which up to four players fulfil orders of increasingly chaotic, physics-based boxes. Landfall’s catalogue includes Totally Accurate Battle Simulator, Content Warning, and Haste.

Patch Notes Document Console Port Preparations

The developers detailed the porting effort in a September 2, 2026 patch note on the game’s official Steam announcement feed. “Believe it or not, we’ve actually been putting in a lot of work behind the scenes to prepare the game for console ports!” the note reads. It explains that the porting work was merged into the main Steam version of the game so that any bugs or broken mods would surface before the actual console launch. The patch, version 2.04.a, also re-added the Caldera and the Kiln biomes to the map rotation.

The same patch added room codes, which the note describes as follows: “This is how players will be able to play cross-platform once our console ports are out.” Under the system, a room code appears on the pause menu in a lobby and can be copied and sent to friends, who enter it through the Join Game option on the main menu. Existing invitation methods still work, and a settings option can hide the code for streamers.

In an October 2, 2026 note for patch 2.6.a, the developers said that integrating the changes necessary to support PEAK on consoles had created bugs in how player and world state are saved, affecting players who reconnected to ongoing games or saved a run and returned later. That patch also replaced the map pool with properly randomized islands after a week in which each day’s selection was either all old or all new maps. A smaller follow-up, patch 2.6.b, arrived on October 6, 2026, addressing issues players experienced when joining in-progress runs.

The porting work follows The Final Ascent, which Landfall describes as PEAK’s final major update, adding the variant biomes Gloom and The Citadel. After the update’s biomes ran exclusively in the map rotation, the developers added a new batch of Gloom and Citadel maps to the daily rotation on August 27, 2026, before folding Caldera and the Kiln back in the September 2 patch. Landfall’s website states the update is available now.

Landfall already ships games on consoles. The studio’s website lists Content Warning and Haste as out now on console, with store links for PlayStation, Xbox, and Switch-family systems for each.
