With their Penumbra game series retired for a while with the release of Penumbra: Requiem, developer Frictional Games is already in development of their next major game project. The company has launched a teaser site for the still unnamed game which will be a first person survival horror title set in an old castle the late 18th century.

Frictional Games that the title will have "all new technology and ideas to become the most advanced, content filled and creative game from our studio to date." The teaser site has some concept artwork from the game as well as a message that is in code that is almost certainly some clue as to the nature of the title. There's no word yet on a release date for the new game.
