Explore 32 rooms, evade deadly robots, and search for puzzle pieces to stop the evil professor in Impossible Mission on the Sega Master System.

Game Overview
"Impossible Mission" on the SEGA Master System is a thrilling, pulse-pounding adventure that’ll test your wits, reflexes, and nerves. Step into the shoes of a secret agent on a mission to stop the nefarious Elvin Atombender from—you guessed it—taking over the world. But here’s the twist: you’ve got just six hours (in-game time, thankfully) to explore his labyrinthine lair, solve clever puzzles, and dodge deadly robots. One wrong move, and those mechanical menaces will send you back to square one!What makes this game a cult classic? Its blend of platforming, exploration, and tension—like a spy thriller meets a high-stakes puzzle box. The digitized voice taunting you ("Stay awhile... stay FOREVER!") is pure ’80s charm, and the non-linear gameplay keeps you hooked. If you love games that reward patience and strategy (or just enjoy outsmarting evil geniuses), this one’s a must-play. Just don’t blame us if you lose sleep trying to beat the clock!"
