Play Sqoon Online

Summary

Sqoon drops you into a side‑scrolling underwater shooter that feels like a retro dive into alien‑infested seas. You command a lone submarine, weaving through scrolling oceanic terrain while blasting waves of hostile creatures that emerge from the depths. The game’s simple yet relentless pacing forces you to balance aggressive firepower with careful navigation, turning each level into a tense cat‑and‑mouse chase. Irem’s 1986 NES release captures the era’s pixel‑perfect charm, delivering crisp sprites and a soundtrack that pulses like a sonar ping. It’s a hidden gem for anyone who loves tight controls and a splash of sci‑fi nostalgia.

Storyline

In Sqoon, the alien rulers of Neptune have exhausted their primary food source—so‑called “man‑ham livestock”—and launch a desperate invasion of Earth. Using advanced technology they melt the planet’s polar ice caps, submerging entire continents beneath a new ocean.

The Earth Defense Army’s general sends an SOS to the notorious pirate Narikeen, demanding that he attack the invaders with his submarine, the Sqoon. Narikeen, true to his ruthless reputation, scoffs at the plea but ultimately agrees to hunt down the alien fleet.

The Japanese version of the game replaces the alien message with a frantic transmission from the U.S. Pentagon, rendered in Romaji: “SOS…SOS… OTOTOSEIJIN NO SHINRYAKU ARI KYSOKU NI KAIMEN JOSYOSERI SQOON SYUTSUGEKI SEYO KAITEI NI HEIWAO!”.
