Hey folks, I've been maintaining a sticky thread over on the Frictional Forums containing all of the currently-known info about the game. The info is sourced so it might be of use to this Wiki. You can find the thread here:
Feel free to scrape it clean for whatever you need. Here's a tiny summary of what we know so far (you can find the sources in the aforementioned thread):
Release Date: Estimated to be toward the end of the summer, probably a bit after.
System Requirements: See here:
Platforms: Windows, Mac OSX & Linux.
Price: The same as or perhaps slightly less than the original Amnesia, which was about £12.99 at launch.
Game Length: Roughly 5 - 6 hours.
Custom Story Support: Unfortunately custom story support will NOT be included.
Commentary: There'll be no commentary track.
Oculus Rift Support: There won't be any native Oculus Rift support added by the developers.
Two actors are known to have provided voices for the game so far. They are:
Toby Longworth: plays Oswald Mandus.
Mark Roper: plays "The Machine" according to his agency profile, not sure what that means!
Hope this is of interest.
