The 7th Guest and The 11th Hour are interactive movies/puzzle adventure games developed by Trilobyte. A third entry in the series, titled The 7th Guest: 3, is being developed for PC, Mac, iOS and Android, Trilobyte co-founder Charlie McHenry told Polygon.
The upcoming adventure will retain the tense atmosphere and puzzle elements that made previous entries so popular and instead of using full motion video like its predecessors, the third iteration will be rendered in real-time 3D. Additionally, the teams is expected to finish The 7th Guest: 3 in 12 to 18 months and they are also planning to launch a Kickstarter campaign in April.
For the moment, I think the scariest part about The 7th Guest: 3 is its unconventional name.
