Aggro Crab’s popular co-op game Peak reached a significant milestone nearly a month after launch. Released on June 16, 2025, Peak challenges up to four players to scale a mountain and overcome various obstacles to reach the top, but one small mistake could end their adventure. The mountain also changes every night to make it funnier and more challenging for players to finish the game.
Peak started out as a “game jam” that was developed earlier this year, and was eventually released as a full game in Steam within a few months. Since then, Aggro Crab’s funny multiplayer title quickly saw a lot of success, recording millions of sales and a growing playerbase that loves its quirky survival gameplay that’s reminiscent of Don’t Starve. There’s also a possibility of Peak to be ported to the PS5 and Xbox in the future, hopefully with crossplay capabilities to allow more players to join the fun.
