Xenophobe - Nintendo NES

Xenos. The very name strikes fear into every colonist's heart. A distress call is received from space stations orbiting your homeworld, then silence. A single ship escapes, piloted by a battered man who tells the tale of pods that hatch into acid-spitting Xenos. A small band of engineers has been dispatched to combat the Xeno threat before it takes over all the space stations and, eventually, your homeworld.
