Aliens
Aliens is an arcade game loosely based on the 1986 movie Aliens. You and a friend play female marines and you must explore and destroy all the aliens that have taken over the abandoned space settlement LV426 Acheron. If you find any survivors, try to rescue them. Besides your normal weapon, there are other weapons that can help you. A Caterpillar P-5000 can also be found and used. Aliens is mainly a horizontal shooter with side view, where the screen scrolls from left to right. At some points in the game you have to look behind the hero and shoot into the screen when aliens approach from a distance, or move in other directions, such as in an elevator. You can also drive into the screen and try to shoot aliens.
Story
The multinational conglomerate Weyland-Yutani Corporation has lost contact with its mining colony Hadley's Hope in LV426 Acheron. As a result, the colonial marines of the USS Sulaco decide to send their team to investigate. The Marines soon discover that the site is infested with an unknown parasitic alien life form and that the crew of Hadley's Hope has either been exterminated or used as a host to raise the creatures' next offspring.
