Zak McKracken and the Alien Mindbenders

The game's narrative is set around archeological mysteries and the paranormal such as aliens, the Bermuda triangle, the Pyramids, the lost city of Atlantis, the "Martian face" (which now we know is not a face at all) and similar...

The story is set in 1997, nine years after the game's production. The plot follows Zak, a writer for the National Inquisitor, a tabloid newspaper; Annie Larris, a freelance scientist; and Melissa China and Leslie Bennett, two Yale University students, in their attempt to prevent the nefarious alien Caponians (who have taken over "The Phone Company", an amalgamation of various telecommunication companies around the world) from slowly reducing the intelligence of everybody on Earth by emitting a 60 Hz "hum" from their "Mind Bending Machine". The Skolarians, another ancient alien race, have left a defense mechanism hanging around to repulse the Caponians (the "Skolarian Device" ), which needs reassembly and start-up, but the parts are spread all over Earth and Mars.

I couldn't play this game from a hard drive, so the loading times take a bit. But at least I found a way not to switch disks, so there's that.
