Sea Wolf is an arcade game by Midway, originally released in 1976. It was a video game update of an earlier coin-operated electro-mechanical (em) Midway game, Sea Devil, itself based on Sega’s 1966 coin-op electro-mechanical arcade submarine simulator Periscope. Midway’s video game version was designed by Dave Nutting and eventually sold 10,000 video game arcade cabinets.

The player looks through a large periscope to aim at ships moving across the virtual sea line at the top of the screen, using a thumb button on the right handle of the scope to fire torpedoes. The periscope swivels to the right and left, providing horizontal motion of a targeting cross-hair. The cabinet features a mixture of video game and older electro-mechanical technology for player feedback. Using back-lit transparencies reflected inside the scope, the number of torpedoes remaining are displayed, as well as a red “RELOAD” light which lights up momentarily when the player has launched five torpedoes. Additionally, when ships are hit on the screen, an explosion “light” is reflected inside the scope. A blue overlay is affixed to the screen to provide a “water color” to the sea. Sounds include a sonar ping and the sound of the PT Boat racing across the screen.
