Xenomorph

Xenomorph is a science-fiction role-playing game viewed from a first-person perspective with an icon-driven interface, drawing comparisons to Dungeon Master . The story is heavily influenced by the Alien film franchise . You play as a janitor on a two-year supply run who wakes from cryosleep to find his ship, the Mombassa Oak, crippled on arrival at the mining platform Astargatis . The human population has vanished. You must explore the platform, searching for microchips and fuel rods to repair your ship while defending yourself against hostile aliens . The game requires managing weapons, medical supplies, keycard access, food, energy, and radiation levels to survive . Critics noted that drawing a map is essential, as it is easy to get lost .

DOS

Released in 1990 by Pandora (Interceptor Micros), with DOS programming by Chris Sawyer, later famous for Transport Tycoon and RollerCoaster Tycoon . The DOS version supports CGA, EGA, or VGA graphics and runs from floppy disk . It retains the same first-person 3D grid-based exploration and icon-driven combat as the Amiga and Atari ST originals . The game, across all versions, was reportedly released incomplete—enemies do not respawn, leaving the base largely empty after reaching the objective, and the food/radiation survival mechanics were non-functional . The interface supports mouse or keyboard control, with movement in 10-foot steps and 90-degree rotations . Nick Reeve composed the soundtrack .
