Viral Co-Op Friendslop Game Sells Over 10 Million Copies Since June 9

Meccha Chameleon has officially crossed 10 million sales. The milestone cements the Steam exclusive as one of the most successful friendslop games in recent memory and is especially notable given the modest circumstances in which it was developed.

Meccha Chameleon is credited on Steam to indie developer lemorion_1224, but it is actually a creation of a two-person team from Japan. While lemorion_1224 handled maps and models, Haganeiro dealt with system management. In just two months, the duo managed to create a compelling hide-and-seek multiplayer game requiring players to conceal their characters by painting them in a way that matches their surroundings as best as possible. The premise is simple enough to be accessible, but its execution allows for a fairly high skill ceiling. More importantly, the average Meccha Chameleon match tends to be filled with spontaneous hilarity that is a direct result of its gameplay design. Those factors, combined with a sub-$5 launch price, have all helped the project become an instant hit following its June 10 release.

Meccha Chameleon is Outselling Cyberpunk 2077 Despite Massive Sale

The viral hide-and-seek sensation Meccha Chameleon is currently outselling some major AAA titles on Steam, despite there being a huge summer sale on.

Meccha Chameleon Celebrates 10 Million Sales 2 Weeks After Launch

Meccha Chameleon developers revealed that their game officially hit 10 million sales as of June 26. Apart from confirming the latest commercial milestone, the terse Steam announcement also thanked fans for their ongoing support. For comparison, Meccha Chameleon reached 5 million copies sold on June 14, four days into its release. Meanwhile, it took two days to hit its first million units, meaning it has not only maintained its immense momentum but actually improved on it, as its daily sales average was higher on June 26 (625k) than the 12th (500k).

Meccha Chameleon‘s imposing success came with almost no conventional marketing. A 24-second video and a few screenshots appear to make up the entirety of the game’s official promotional material. Yet its premise is immediately clear from those limited samples, and its gameplay more than delivers on the initial promise while simultaneously being extremely accessible. The end result of those distinctive circumstances is one of the strongest organic word-of-mouth campaigns of 2026.

Hilarity with Variety: How Meccha Chameleon Succeeds on a Fundamental Level

As much as hilarity, variety is part of the game’s core appeal, with the day-one version of Meccha Chameleon already offering three distinct gameplay modes, each with its own twist on the intuitive hide-and-seek ruleset. At the same time, the freestyle painting mechanic creates plenty of funny moments while giving skilled players room to improve. That gives the game a strong improvisational quality, thus checking that fundamental multiplayer box of making no two matches feel quite the same.

The game’s community has also become one of its biggest assets. Official Steam Workshop support gives players access to user-created content, and the best Meccha Chameleon Workshop maps can dramatically change the rhythm of a match by introducing new textures, props, layouts, and lighting conditions. That is, naturally, highly relevant in a game built around camouflage, as every new environment effectively becomes a unique puzzle for both hiders and seekers. None of that guarantees that Meccha Chameleon will remain this visible indefinitely, but it does inspire hope in its medium-term prospects.
