Popular co-op title Peak has received its first major content update, adding a brand-new biome to the game, new items, and other surprises alongside bug fixes. The indie title from Another Crab’s Treasure developer, Aggro Crab, and the Swedish indie studio Landfall, continues to be incredibly popular, and this latest update will likely keep Peak at the top of the Steam charts.
Impressively, Peak initially started out as a Game Jam title, eventually evolving into a full-fledged title that launched on Steam on June 16, 2025. From there its popularity spread like wildfire, with Peak eventually selling over 5 million copies in just a month, pushing the developers to continue updating the title. The game has seen plenty of smaller updates, but recently, Aggro Crab has continued to tease Peak‘s first major update, a patch that introduces a bunch of new content and cosmetics for players to dig into.
For many fans, the biggest piece of the Mesa Update for Peak is the new biome itself, which developer Aggro Crab showcased in a short trailer. For the next week following this update, the Mesa will be replacing the Alpine location in every single run that players undertake. However, after that point, the maps will randomize between the two, adding an element of uncertainty to runs. As the trailer teases, players appear to have plenty of new elements to contend with, including a tornado as well as the hot sun.
The help players, Aggro Crab has added new items to find on their climb, like Sunscreen and Aloe Vera, balloons, and even parasols to help block out the sun’s effects. There are tumbleweeds that roll across the map, and players can add scout cannons to their available selection of Peak climbing tools to help reach higher ledges in their pursuit of conquering the landscape. Dynamite has also been included in this update, which could present a number of opportunities for trolls to potentially mess with their fellow players.
So far, 2025 has been a huge year for fans of co-op games, as there have already been a variety of games that have found their way near the top of sales charts. In terms of indie titles, REPO, Peak, and Schedule 1 have all seen major success this year, furthering the dominance that co-op games have seen on Steam in particular. For the AAA crowd, Elden Ring Nightreign and Monster Hunter Wilds have also seen their fair share of popularity at times as well, with both games continuing to push out new updates and content for players.
