Play Navy Blue (Japan) Online
Command a submarine, navigate the Pacific, sink enemy ships, manage torpedoes and fuel, and outsmart destroyers in this strategic naval warfare game from 1990.

Navy Blue is a 1990 Nintendo Entertainment System release from publisher Pack-In-Video. It arrived late in the NES lifecycle, a time when developers were pushing the hardware with more complex simulations and strategy games. This one fits squarely into that niche, offering a methodical and demanding take on submarine warfare.
You command a submarine, navigating a grid-based map of the Pacific Ocean. Your objective is to sink enemy warships and freighters while carefully managing your limited supply of torpedoes and fuel. The core gameplay involves plotting a course on the strategic map, then switching to a first-person periscope view to manually aim and fire at targets. Enemy destroyers will hunt you relentlessly, using depth charges and their own sonar pings that grow louder as they close in. The pacing is slow and deliberate, demanding patience and foresight; a single mistake in navigation or a wasted torpedo can lead to a mission failure. It feels like a tense game of cat and mouse where you are always the mouse.
