Sea Wolf

Sea Wolf is an arcade game by Midway, originally released in 1976. 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.
