A blast from the past has landed on Steam in the form of a bundle for The 7th Guest and The 11th Hour. Released in the mid-nineties, the interactive puzzle adventures were popular with PC gamers, and were among the first games to take advantage of the increased capacity afforded to them via CD-ROM.
Night Dive Studios have handled the port, and will continue collaborating with Trilobyte Games for the upcoming Kickstarter campaign for the third game in the series, which is simply called 3. More details on that when the campaign launches. For now, here's a link to the bundle on Steam.
