Play Sqoon (Japan) Online
Dodging alien depth charges in a wobbly pink sub feels janky at first, but nailing those awkward rescues while the killer soundtrack plays? Weirdly addictive. Watch out for octopi.

Sqoon is a 1986 NES release from Irem, a developer known for arcade style games that often felt a bit different from the rest of the library. It arrived during a period when the console was flooded with shooters and platformers, offering a strange, underwater take on the genre that was immediately noticeable for its oddball charm and specific, demanding controls.
You pilot a pink submarine, navigating a multi-level ocean to rescue stranded humans from floating platforms. Your main objective is to collect these survivors and then ferry them to a safe surface ship, all while fending off a relentless barrage of enemy sea creatures and projectiles. The signature mechanics involve a slightly unwieldy, momentum-based movement for the sub and a unique dual weapon system: you fire standard shots forward and can also drop timed depth charges directly downward. The pacing is frantic, and the difficulty is steep, largely due to the sub's sluggish handling and the screen quickly filling with aggressive foes. It feels like a constant, chaotic struggle against the controls and the enemy spawns, creating a uniquely tense and sometimes frustrating experience.
