About Poseidon Wars 3-D
Battle Stations! Battle Stations! Your country is being attacked. You'll be fighting on the U.S.S. Poseidon; an armor-plated attack cruiser with radar, sonar, 76mm cannons and surface-to-surface missiles. First come the training rounds. They'll throw everything they have at you... jets, cruisers, torpedoes, cannons. And then the fun really starts! Combat missions! You're on the open seas. You have blips on the radar. Line up your gunsights and let 'em have it. You pick up an enemy cruiser on your sonar. Get ready with an armor piercing missile and send them to Davey Jones locker. If you complete your missions, you will be awarded with the Navy's highest honor... a promotion to Fleet Admiral.

Before you buy
There are two releases, the US cart and the European cart. Loose they cost about the same, but the European cart costs much more complete. The SegaScope 3-D Glasses are optional, because the game also has a 2-D mode. The US cart sits above the middle of the price range for US games.
