Poseidon Wars 3-D is one of those weird, niche Sega Master System gems that makes you go, "Wait, they did what with a light gun?" You’re basically in a naval battle, blasting enemy ships with the SegaScope 3D glasses—which, yeah, actually worked (sort of). The 3D effect is more "whoa, that’s kinda neat" than mind-blowing, but it’s still a trip seeing those pixelated waves pop out at you.

Gameplay’s straightforward—point, shoot, don’t get sunk—but there’s something oddly satisfying about lining up shots with the light gun while dodging torpedoes. Just don’t expect deep strategy; it’s pure arcade chaos. And hey, if you ever find a working pair of those glasses, it’s worth a laugh just for the novelty.
