Charlie McHenry, co-founder of original developer Trilobyte, announced the project to Polygon. The 7th Guest: 3 retains the same emphasis on puzzles as its predecessor, but is now rendered in realtime 3D as opposed to the full motion video of the 1993 original, which was one of the earliest games to ship on CD-ROM as opposed to floppy disks.
"In the world of The 7th Guest: 3, you will re-enter the mysterious and magical mansion, newly restored with games, puzzles and artifacts," said McHenry. "But it is still haunted, as players will soon discover. You will learn more about what happened on that terrible night, and discover the real story and previously hidden secrets of the gaming world's most mysterious toymaker."
Some of the original 90s development team are returning for The 7th Guest: 3, and the team is planning on launching a Kickstarter campaign for the game next month provided they can't secure funding by alternative means.
Development on The 7th Guest: 3 is expected to take between 12 and 18 months, according to McHenry.
