UFO 2 !?
UFO was a trilogy of games, aftermath , aftershock , and afterlight.
Aftermath had you dealing with the effects of social collapse just after the alien invasion, Aftershock (shit game) had you dealing with Earth after Aftermath, Afterlight had you deal with Mars which had been cut off from earth for the duration of the previous 2 titles.
good games (except aftershock) really close to X-com playstyle. I like the way the story progresses through the 3 until you get closer to the truth behind the invasion.
and there i go talking shit about another game that is pretty similar but not what your talking about
UFO: Extraterrestrials i have no experience of.
