LEMORION is the developer behind Meccha Chameleon, the hide-and-seek game that grew from a 110,000-wishlist launch to a Steam release, then a Switch 2 release announced during Nintendo's September 9, 2026 Direct. LEMORION is credited alongside HAGANEIRO as co-creator on post-launch updates. HAGANEIRO is also credited on post-launch updates.
LEMORION announced Meccha Chameleon as a solo-developed multiplayer hide-and-seek game for PC via Steam, with a June 10 launch date and a wishlist that had passed 110,000. The pitch was simple: players paint their plain white avatars to camouflage against 3D environments and avoid the oni team, with support for up to 10 players and three modes.
The launch was fast. LEMORION announced 500,000 copies sold within two days of the June 10 release, with 200,000 on day one and a concurrent peak of around 40,000 on June 12. The game ranked 7th on Steam's global top sellers chart and 3rd in Japan, with user reviews at 74 percent positive. LEMORION credited HAGANEIRO as a co-creator and outlined an update adding a point system tied to the hunter's field of view, a new official map, and two new poses, alongside a 20 percent launch discount running until June 17.
Post-launch support continued on July 11 with update 2.6.0, released by LEMORION and HAGANEIRO, adding the HIKAKIN Museum collaboration map, a controller support alpha that does not cover UI operations, region tags for Japan, South Korea, and East Asia, a doppelganger hit-detection fix, and a widening of the hunter's field of view from 100 to 105. Two days later, LEMORION added the Egypt map alongside the Hikakin collaboration map, plus random map selection toggle support and random elements to the Penguin Hotel map. By then the game had sold over 15 million copies in less than a month.
On September 9, 2026, Nintendo announced during its Direct that the Switch 2 version of Meccha Chameleon would launch immediately after the broadcast. The same Direct confirmed Xenoblade Chronicles 3 Nintendo Switch 2 Edition for December 3, 2026.
