Sega Master System / Mark III / Game Gear
The first impression you'll get of this is a sort of Impossible Mission variant, featuring an athletic sort of guy armed with a laser pistol, out to put paid to an evil tyrant's plans for world domination by entenng his base, avoiding the many robot guards that are scattered about and collecting the codes that will result in the base's destruction.
The thing is, when you actually get into the game, it falls down on the factor that you have to keep track of all the codes required, which means you have to keep stopping the game, scribbling down the code, and carrying on, resulting in a very frustrating time all round.
