Aliens: Alien 2 is an arcade platformer (or run'n'gun if you like) featuring Ripley on a planet infested with aliens. Armed with only a basic gun at first, she faces facehuggers that come out of alien eggs. After having dispatched a face hugger, the egg may be shot to reveal an item. Items may be hand grenades, stronger guns or wing items which make her jump longer. The game was scheduled for release in 1987, but was canceled. The prototype was leaked onto the internet in 2009.

Alien³ was released after the Alien 3 film. After success on the Super Nintendo and Genesis platforms, the game was built and ported to other systems, including the Commodore 64 and Game Gear. The game is set on the world of the film, Fury 161, but the gameplay has more in common with the film Aliens, throwing wave after wave of enemies at the player.

A platform shoot-em-up hybrid from Sega for one to four players, selected from either Joe (yellow), Mary (red), Lee (blue) and Edgar (green). The action takes place over a number of sideways scrolling levels, the bulk of which consist of straightforward platform action. On some levels, however, there are jet packs for the players to collect, and the gameplay's emphasis switched to that of a standard, sideways scrolling shoot-em-up. The object of the game is to destroy an army of robots that have taken over an Earth colony satellite station. Each level has a boss character that must be destroyed. Upon its death it releases a door key that must be used to exit the level. Weapon and character power-ups can be collected to aid players in their task. Due to its potential for four-player shoot-em-up gameplay, Quartet's gameplay feels vaguely similar to (though by no means as accomplished as) Atari's 1985 classic, "Gauntlet".
