Indie multiplayer game "Meccha Chameleon" has achieved an explosive launch, selling a staggering 15 million copies in just 26 days after hitting Steam on June 10 for $5.99. This blistering pace builds on its previous milestone of 10 million copies sold in only 16 days.
The premise is a refreshingly simple twist on hide-and-seek: hiders use blank white avatars and a paintbrush to camouflage themselves against dynamic backgrounds like bricks or statues, while seekers frantically try to sniff them out.
What makes this feat wild is that a tiny team of just two developers—from LEMORION and HAGANEIRO—built the entire game in under two months with zero marketing budget. Instead, viral clips from streamers, VTubers, and TikTok drove the historic growth. Video game analyst Daniel Ahmad labeled it 2026's fastest-selling title, and the devs are already teasing an upcoming collaboration with a major Japanese star.
