I can't remember exactly but it wasn't a "happy ending" game series. These came out a long time ago and there were a series of them, firsr being in 2000. But it was the first I really heard about the Illmunati being "bad guys". They also brought up human vaccines and "mods" not quite working out the way people hoped except for the ones behind the scenes pushing them on people. Overly simple explanation of the gist.
