I remember reading about Twilight Software and their adventure game a long time ago, but it looks like it's coming out soon.
"The CD-ROM based adventure game features a super-simple interface, 240 scenes, 17 different locations, and 11 characters. Filmed and photographed entirely on location in beautiful Sydney, Australia, the game immerses the player in a mystery in which a kidnapped uncle has disappeared in a grim underworld of treacherous characters and plot twists."
Gamershell has all the details. Be sure to visit Twlight Software's website for more information about The Sydney Mystery!!
