Japanese developer LEMORION announced on June 15 that their viral hide-and-seek party game Meccha Chameleon has sold over 2 million units. This announcement came only a day after the game hit the 1 million mark, and only five days following its initial Steam launch. Being a self-published indie project, the title’s overnight success has earned widespread awe from fellow developers in Japan.
Mecha Chameleon is a multiplayer hide-and-seek game centered around drawing and camouflage. Players control a plain white character and compete in hide-and-seek matches across 3D maps filled with objects. The seeker must hunt down the hidden players, who are eliminated if shot.
The twist is that players can freely paint their own characters with colors and designs of their choice. You can also sample colors from points scattered around the environment, allowing you to blend into the surroundings. While you can also simply hide behind objects or on high ground, the key is to make use of the game’s drawing mechanics to disguise yourself as part of the scenery. The result is, as you’d expect, a spectacularly chaotic hide-and-seek experience.

The game supports online multiplayer and includes several modes, such as a traditional format where one seeker must find everyone before a timer runs out, a mode where discovered players become seekers themselves, and another in which everyone hides first before competing to see who can locate all the others the fastest.
Currently rated “Very Positive” on Steam, Mecha Chameleon was developed by game creator LEMORION. On their X account, they credit HAGANEIRO as a co-creator, suggesting that the game was created by a team of two people at least. Additionally, the Steam store page suggests the title is self-published.
Mecha Chameleon had already attracted significant attention before launch thanks to its catchy concept, with Steam Wishlists surpassing 500,000 on the eve of release. The momentum seems to have not only carried over but accelerated following launch, as the game quickly sold over 5 million units and peaked at over 130 thousand concurrent players (SteamDB). At the time of writing, Meccha Chameleon’s popularity seems to come primarily from English-speaking users, as over half of the title’s Steam reviews are in English.

Following LEMORION’s announcement of the game passing the 2-million mark yesterday, industry peers in Japan couldn’t help but comment on how odd-defying Meccha Chameleon’s success is when contrasted with the market’s current conditions. Mixi and Sega game producer Taira Nakamura said, “Even without spending money on promotion, they’ve sold 2 million copies in 5 days, albeit at a low price point. This is an unthinkable achievement for the game industry and game companies.”
He theorizes that Meccha Chameleon’s commercial success comes from its high popularity among streamers, and that the game itself was likely designed (consciously or unconsciously) with the idea of “being fun to stream” at its core. “For those of us who grew passionate about games during a time when streaming didn’t exist, this is a perspective we don’t consciously think about. I don’t think there will be any commercial games coming out in the future that don’t take streaming into account, so perhaps an even greater update in our mindset is necessary,” he commented.
Meccha Chameleon is available for PC (Steam).
