The test software is now available to download ahead of the start of gameplay, and requires 2.2GB of free space. Participants didn’t sign an NDA, but Nintendo requested in the playtest terms and conditions that users refrain from sharing any details about it — which has gone about as well as can be expected. While Nintendo has already started issuing copyright strikes to take leaked media offline, screenshots and information about the playtest are still available across websites like X and Reddit at the time of writing.

This appears to be Nintendo’s attempt to develop its first MMO (massively multiplayer online) style game. According to the game description, “the goal is to work with others to fully ‘develop’ a massive, expansive planet by utilizing creativity and framed resources.” Players will encounter “new lands, enemies, and resources” as they progress, and utilize “Beacons” that create zones to develop the environment around where they’re placed. These Beacon zones are personal — players can only “move, lift, or edit items” in zones they have placed, and cannot edit anything within someone else’s Beacon.

There’s a separate social hub called the “Dev Core” where players can level up, obtain items, and interact with each other. Nintendo also describes “UGC (User-Generated Content) features” for creating and sharing custom content, but players are required to pass an in-game test “to show that you understand the importance of respectful communication” before this capability can be unlocked.

At a glance, the game shares some similarities with family-friendly MMO’s like Minecraft and Roblox. The IP is either entirely new (in that it doesn’t feature any recognizable Nintendo characters) or it’s a placeholder for the game system itself — meaning it could be part of an existing franchise at release. All we know for sure is that previous speculation suggesting the playtest would bring GameCube titles to the Nintendo Switch Online service can probably be put to rest.
