Developer Castello is running a playtest for Moon Crashers on Steam ahead of the game's planned July 28, 2026 launch.
Developer Castello announced Moon Crashers in late June 2026, a cooperative survival craft game set on the moon. The game supports online co-op for up to four players, who crash-land, gather wreckage and resources, and build a rocket to return to Earth. Low-gravity physics affect movement and vehicle handling, creating chaotic gameplay including accidental teammates being launched by jetpacks and buggy rollovers.
In early July, Castello launched a playtest on Steam that runs for several weeks, ending just before the July 28 release. The playtest allows up to four players and includes the core mechanics: using jetpacks and grappling hooks to explore via buggy, with the risk of an explosion from a failed weld. The developer is collecting feedback through a short survey and permits streaming with a disclaimer.
The full game is scheduled for release on July 28, 2026, on PC via Steam. The short playtest window suggests final polish and last-minute feedback gathering before launch.

Developer Castello released Moon Crashers on Steam on July 28, 2026. The game is a cooperative action-adventure for up to four players, set on the Moon, where players take on the role of astronauts who crash-landed and must gather materials to build a rocket and return to Earth. The lunar surface features deep canyons and sprawling craters, and players explore using jetpacks, grappling hooks, and vehicles such as a beat-up buggy, trucks, and motorcycles. They collect wreckage from spacecraft and valuable resources, while also mining ore in caves and fighting red spherical enemies. The game supports online co-op, with solo play possible but not recommended. A failed weld can cause the rocket to explode, turning it into what the developer calls the galaxy's biggest fireworks. The standard price is 920 yen, with a 40% launch discount bringing it to 552 yen until August 4. This is Castello's third commercial release and their first non-VR game, following their previous VR titles.
