Duck and cover! Guido the computer generated killer is on the loose and he's armed to the teeth. To get a piece of this action for yourself, press Up, Right, Right, Down, Down, Down, Left, Left, Left, Left, A, Up, B, Down, C, Left, Down, Start. When the game beings, take the guy with the missile launcher from the group and fire three times. He should spin around and disappear and, in his place, a character called Guido should join with a new laser weapon. And one hit from this little baby should kill everything first time. (Jeeps and tanks may take a few more shots, though.)
