New co-op adventure free game climbs Steam trending chart shortly after release

Steam sees many new releases every now and then, and not all of them cost money. To be specific, each week, a handful of free games get spotted on the platform, and That One Otter Game is one of them. This freebie became available on July 15, 2025, and shortly after the release, it secured a position in the top 10 "New & Trending" chart.

Developed by Crayon Coded, That One Otter Game is described as a mysterious co-op adventure title that's designed for two players. This freebie lets you step into the paws of young otters who must work together to prove their worth. The main objective is to complete silly park challenges.

These challenges range from racing a hyped-up zebra, catching a panicked penguin, and hauling a stolen radio up a mountain. With each of the missions complete, players get their stamp cards marked, which is basically how you progress in this free Steam game.

Players who tried this free game note that the missions blend puzzles and platforming challenges. Some of them even encourage you to opt for a creative approach.

The game's world is filled with interactable objects, and the overall theme is colorful and lively. There are a variety of NPCs throughout, and players can find hidden collectibles, which allows the otters to change their appearance.

Now, while That One Otter Game is a co-op title, it only supports local co-operative play. There's no single-player mode available either, which means the story can not progress without a second player. You can learn more about this free game on Steam from the video attached below.
