Members - The Mysterious Corporation mod for Portal

Set inside a hidden scientific corporation, a strange piece of technology is hidden inside a maze-like underground facility. A person is sent in by the Government to find out what is going on, only when he arrives, he discovers that nobody has been there in months. Now he has to work their way through the facility, solving puzzles and slowly getting closer to solving the mystery of The Corporation. The Corporation is intended to be in the style of Myst, with very difficult puzzles that have hidden and obscure solutions. Also note that the mod will eventually be able to be run on Half-Life 2 Episode 2's engine, and also that an alternate point of view will be developed, only instead of puzzle, it will instead be a first person shooter.
