New Open-World Co-Op Game on Steam Is Absolutely Blowing Up

A new 16-player open-world game on Steam called Moon Sweepers has surpassed 50,000 concurrent players shortly after launch, making it one of October 2026's most successful releases. Two-person indie studio DragDrop Games developed Moon Sweepers , which has received mostly positive reviews from Steam users at the time of writing. Moon Sweepers could fit into Steam's popular cleaning-game subgenre, led by games like PowerWash Simulator . However, DragDrop Games' title adds a few interesting twists to the formula, making it a great fit for automation games too.
