The indie multiplayer game Meccha Chameleon has achieved remarkable success, surpassing 15 million sales on Steam less than a month after its June 10 launch. Developed by a two-person team in just two months, the game features a unique paint-and-seek gameplay loop.

In Meccha Chameleon, players are divided into Seekers and Hiders. Hiders must use paint to camouflage their characters against the environment, while Seekers attempt to locate them before time expires. The game has gained significant traction with streamers, who have showcased creative painting strategies.

The developer, lemorion_1224, announced the sales milestone and teased an upcoming collaboration with a "famous Japanese star" via a Steam community post. This announcement has sparked considerable fan speculation on social media platforms.

Fans are actively guessing the identity of the collaborator, with suggestions including prominent Japanese YouTuber Hikakin and watercolor painter and content creator Harumichi Shibasaki. Shibasaki has prior experience with game collaborations, having participated in Minecraft's 15th anniversary event. The developers intend to reveal the collaborator next week.

Meccha Chameleon has been receiving frequent updates and patches since its release. The developers have also noted that the game has inspired real-world adaptations of its gameplay. In addition to the core game, guides for Meccha Chameleon, including tips, map breakdowns, and multiplayer instructions, are available.
