Gumshoe is a video game developed and published by Nintendo for the NES and released on June 6, 1986 in North America, and on June 15, 1988 in Europe. Gumshoe is played using the NES Zapper. The game was designed by Yoshio Sakamoto.
Mr. Stevenson walks continuously to the right, and will jump if shot with the NES Zapper. The player must also shoot enemies as they appear on screen. Shooting Mr. Stevenson to make him jump will not subtract from the player's ammunition. Shooting obstacles, or an empty area, however, will subtract one bullet from the total. Having Mr. Stevenson grab red balloons will add bullets.
Mr. Stevenson is an ex-FBI agent turned detective. He receives a ransom note from Mafia boss, King Dom, who has kidnapped Stevenson's daughter, Jennifer. Stevenson must collect five "Black Panther Diamonds" within 24 hours in order to see his daughter again.
