Overview
Poseidon Wars 3-D is a Master System rail shooter in which you play as a US Navy cadet and must face a series of naval missions commanding a submarine to advance your military career. It was developed and published by Sega and released in 1989, receiving mixed reviews from critics by the time, despite being a quite fun and dynamic game, considering it’s 8-bit limitations.
The game, which we have here set to be played online, on browsers (HTML5), features a first-person, simulator-style perspective and supports SegaScope 3-D, but can be played without this peripheral. The screen displays instruments such as radar and sonar, essential for locating hostile units to shoot at them and/or anticipate their movements. You also need to manage fuel and avoid or destroy enemy projectiles to prevent receiving critical damage.
About the game
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 ‘cm have it.
You pick up an enemy cruiser on your sonar. Get ready with an armor piercing missile and send them to Davy Jones locker. If you complete your missions, you will be awarded with the Navy’s highest honor…a promotion to Fleet Admiral.
Best of all, you can play it in SegaScope 3-D or in 2-D. So everyone can play. But command the Poseidon well, or the enemy will send you to the briny deep!
