This 1990 Aliens game by Konami has insanely colorful graphics, and simple but fun gameplay. In certain areas, this weirdly blond Ripley has a radar that shows the positions of snearky aliens that suddenly pop up from vents and grates to attack. The music consists of well-composed high energy FM tracks, certain themes seem to be inspired by soundtrack of The Terminator.
