Play Space Gun (Europe) Online
Blast through corridors of nightmare aliens while trying not to accidentally fry hostages in neon jumpsuits—your gun feels heavy, but timing shots between dodges makes it click. Boss fights are gloriously janky screen-filling monstrosities.

Space Gun was a Sega Master System release in Europe, though it never saw a release in other regions. Developed by Taito, it arrived late in the system's life, offering a sci-fi action experience that felt distinct from many of the platform's other titles. The game puts you in the role of a space marine tasked with clearing infested space stations and alien vessels, a straightforward premise that fits right in with the era's arcade-inspired shooters.
You control a marine who moves through tight, side-scrolling levels, shooting a variety of alien creatures while being careful to avoid hitting human hostages. The main objective is simply to survive each stage, eliminating enemies and navigating environmental hazards. Signature mechanics include a chargeable weapon that can be powered up for stronger shots, and the constant need to distinguish between hostile aliens and rescue targets. The pacing is fast, and the difficulty is unforgiving, with limited continues and aggressive enemy patterns. It feels tense and demanding, rewarding precision under pressure.
