Play Navy Blue 90 Online
You plot moves on a grid, holding your breath as enemy subs lurk unseen—one wrong turn and your destroyer’s just pixel smoke. That first perfect torpedo hit? Pure payoff.

Navy Blue 90 is one of those Game Boy games that sneaks up on you—it looks simple at first glance, but before long, you're hunched over your screen, sweating over torpedo trajectories and flanking maneuvers. The grid-based combat feels like a mix of Battleship and chess, except every wrong move costs you a destroyer.
I remember my first playthrough—I sent my cruiser straight into enemy waters like an idiot and got obliterated by a submarine I didn’t even see coming. The learning curve’s steep but fair, and there’s something weirdly satisfying about watching those little pixel explosions when you finally nail a perfect strike. Graphics? Barebones. Tension? Off the charts.
If you’ve got a soft spot for tactical games that don’t bother with tutorials or hand-holding, this one’s a blast from the past worth revisiting. Just don’t blame me when you lose track of time trying to avenge your sunk fleet.
