Impossible Mission for the Nintendo Wii is an action-adventure platformer that revamps the classic 1984 Commodore 64 game. Players take on the role of a secret agent tasked with infiltrating a high-security facility to stop an evil genius. The gameplay involves navigating through a series of rooms filled with puzzles, traps, and robotic enemies. With a combination of running, jumping, and using gadgets, players must hack computers, collect items, and piece together a password to thwart the villain's plan, all while racing against the clock.
