Meccha Chameleon just dropped the biggest indie flex of 2026: 10 million copies sold in 16 days on Steam, all from two Japanese devs who cooked this hide-and-seek paint party in Unreal Engine 5 over two months flat. Launched June 10 at a cheap $5.99 (even less on sale), it peaked at 340K concurrent players without a single ad dollar spent — just pure Twitch chaos and players turning into walking art pieces blending into maps. Steam charts and dev posts confirm the numbers, blowing past games that took months or years with huge teams.
