Sea Wolf

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.

Sea Wolf is time-limited, with the player having an opportunity to win bonus time by reaching an operator-set score.

The player's score is shown on the bottom half of the screen as well as the high score, one of the first known instances of a high score in a video game.

Targets include destroyers, a fast moving PT Boat, and mines floating across the screen can that serve as obstructions.

Sea Wolf for Commodore 64 is currently worth €8.32 loose, €22.16 complete in box, and €30.39 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Sea Wolf has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Sea Wolf, loose is €8.32 and CIB is €22.16 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
