Alien Storm

Developer: Sega

Alien Storm on the Mega Drive drops players into a chaotic sci-fi beat 'em up where three genetically enhanced operatives clear city streets of an alien invasion. Blending close-quarters brawling with occasional ranged attacks and gadget-powered special moves, the game pushes fast-paced, enemy-filled stages capped by memorable boss encounters. Cooperative two-player play amps up the frantic tussles, while varied enemy patterns and limited lives keep difficulty brisk and rewarding. Its arcade roots show through vibrant sprites, catchy music, and pick-up-and-play immediacy—perfect for nostalgic sessions or newcomers wanting a high-energy retro action romp.
