Almost three decades ago, a game called McDonald’s Treasure Land Adventure was released for the SEGA Genesis console – and like many video games released by fast-food franchises over the years (remember Taco Bell’s Moto X game?), It was quickly forgotten by everyone except a small group of enthusiasts. Unlike many of these games, however, this one was teased as harboring a secret, which has just been discovered.
McDonald’s Treasure Land Adventure was a Genesis game developed by Treasure. One of the programmers who worked on the title, Masato Maegawa, has spent years teasing enthusiasts about a hidden Easter egg hidden in the game. Intrigued amateur detectives have gathered the few clues revealed over the years.
With that information, the Twitter user “Unlisted Cheats” was able to solve the mystery – and, well, it’s disheartening and incredibly scary. When entering a password using a specific and rather long series of button presses, McDonald’s signal at the beginning of the game will become a 3D object.
Users can then move the object using the directional pad or switch to a different model, including a rustic spaceship, the SEGA logo and a few simple cubes. Solving the mystery is fun and all, but the Easter Egg itself is not very interesting – except for the disturbing music that accompanies it.
The cheerful beep in the retro game quickly becomes a series of chaotic riffs not unlike what you would expect to hear in a classic cult horror movie. If someone had accidentally tripped over this Easter Egg like a child innocently playing a McDonald’s adventure game, they may have been reluctant to start the game a second time.
