Meccha Chameleon hits 15 million copies sold, announces upcoming Japanese star collaboration

Indie hide‑and‑seek game Meccha Chameleon has sold more than 15 million copies on Steam less than a month after its 9 June 2026 launch, making it the fastest‑selling and best‑selling title of the year. Developers Lemorion_1224 and Haganeiro, a two‑person Japanese team, announced on Steam: “We hit 15 million in sales! Thanks a million! Get ready for a new collaboration with a famous Japanese star next week!”

The game reached 1 million sales in four days, 10 million in 16 days and 15 million in 25 days, with peak concurrent players exceeding 340,000, surpassing major multiplayer titles. A recent patch added controller‑support, refined the paint brush, and introduced new modes such as Reverse Chicken Race. The team also teased a “collab map” featuring an unnamed Japanese celebrity.

No marketing budget was spent; the surge stemmed from word‑of‑mouth, viral gameplay videos and social‑media sharing. The success highlights the impact of low‑cost indie titles in the 2026 gaming market.
