Games like alien storm

Alien Storm (エイリアンストーム) is a 1990 beat 'em up shooter arcade game by Sega. It was later ported to the Sega Mega Drive/Genesis and Master System. The Mega Drive version was released on Wii's Virtual Console in 2007 and was also included on Sega Mega Drive Ultimate Collection for Xbox 360 and PlayStation 3.

A homicidal alien race is invading Earth, and the only thing that stands between them and world domination are a special forces team known as the "Alien Busters", composed of Karen (absent in the Master System version, named "Karla" in some versions), Garth (named "Gordon" in some versions) and Scooter (the robot, named "Slammer" in Master System and PAL versions).

Alien Storm is a side-scrolling beat 'em up. The game resembles Golden Axe, with a similar artistic style, three playable characters (a man, a woman, and a novelty character) and pick-up or power-up special attacks. The player (one player only on the Master System version, up to two players on the Mega Drive version, three on the arcade version) selects from the three different characters to embark upon a quest to save the Earth from an alien invasion.
