The cooperative adventure game "PEAK" is rumored to have ESRB rating information for a PS5 version, suggesting a potential PS5 release, though this has not been officially confirmed. The North American Entertainment Software Rating Board (ESRB) website does list a PS5 rating entry for "PEAK," rating it E10+ (suitable for ages 10 and up) with content descriptors for "Fantasy Violence" and "Users Interact."
IGN cited ESRB information to suggest a PS5 version. Following the convention that ESRB ratings usually appear close to a game's release window, an official announcement may not be far off. Some analysts also pointed out that since the PS5 version has a rating record, Xbox and Switch 2 versions are equally possible, but so far there has been no official statement.
"PEAK" previously garnered attention on Steam. As of August 2025, the game had sold over 10 million copies at a price of $8. Its low price and suitability for playing with friends were part of the reasons for its spread. Developed jointly by Aggro Crab and Landfall Games, the title quickly became popular after its release in June 2025, with its peak concurrent players on Steam exceeding 170,000, making it one of the most successful indie games of the year.
