Play Space Gun Online
Blast through tight corridors as alien horrors swarm from every angle—scrounge ammo, rescue survivors, and pray your trigger finger’s faster than whatever’s skittering in the dark.

Space Gun was a Sega Master System release from Taito, arriving late in the console's life. It was a side-scrolling shooter that felt right at home among the platform's other action titles, offering a straightforward sci-fi premise without much pretense.
You control a marine navigating a derelict spaceship, moving from left to right across each screen. Your main goal is to blast through waves of alien creatures while searching for human survivors to rescue. The gameplay hinges on managing your limited ammunition, switching between a standard rifle and a more powerful, but scarce, flamethrower. The pacing is relentless; enemies pour from vents and ceilings constantly, demanding quick reflexes. It feels like a tense, claustrophobic fight for survival where every shot counts.
