Aliens: Alien 2

Aliens: Alien 2 is a Square-developed action platformer and shooter released in 1987 for the Microsoft MSX and Family Computer Disk System.

Playing as Ripley, you explore an alien-infested planet with a basic gun. Facehuggers emerge from alien eggs, which can be shot after the enemy is defeated to reveal useful items such as hand grenades, stronger weapons, and wing items that extend Ripley’s jumps. The game also features snakes among its hazards.

After clearing the planet’s surface, Ripley enters a complex and confronts a giant, fully grown alien boss before continuing into the facility.
