One of 2025's surprise hits was Peak, a co-op climbing game that was created in a mere four months by studios Aggro Crab and Landfall. It caught fire on Twitch and in every friend group hooked on so-called "friendslop" since 2023's Lethal Company.

Even though there has been a strong trend of co-op games in the past few years, Aggro Crab and Landfall weren't expecting Peak to explode in popularity.

It's all mighty impressive for a game that has still maintained its charming game jam-like quality—something Kaman said was important to maintain as the studios updated it. Wobbly character models and opportunities for goofy pratfalls are why these games catch on so quickly.
