Ah, a true masterpiece. Today, there are games that eat a whole hard disk and still fail to deliver a fraction of suspense that UFO: Enemy Unknown does in 15MB of glory. The game begins with the isometric view of Planet Earth and the doomsday clock ticking its minutes past the New Year's Eve of 1999. This is the Geoscape. And you first step is to setup your first X-COM base. You begin with a handful of engineers, scientists and soldiers, some supplies, a radar, and several inferior spacecraft designed to intercept aliens coming to Earth.
