Frictional Games has teased a “new super secret project” on its official blog.

The Amnesia: The Dark Descent developer gave few details, except to say that the game would be a first-person horror title.

“One of the things I was most disappointed with in Amnesia was that it never really managed to deliver any deeper themes, but was more like a shallow fright-fest,” said Frictional Games’ owner Thomas Grip.

“For the new project we want to change that and really try and bring a certain theme to the front.

“Our hope is that this will create a very special experience, creating horror in a much more disturbing way.”

According to Grip, playtesting had just begun on the title, although the current design was bound to change.

“While we do not want the project to go on forever, we want to use our good financial situation the best we can and make sure we do not just rush something out (which we did with Amnesia actually),” he said.

The game would probably be out sometime in 2014, said the developer.

In the interim, the Frictional-produced Amnesia: A Machine For Pigs – an Amnesia sequel developed by thechineseroom – would be released.

Grip said its release would be interesting in many ways.

“First of all it is a big experiment for us to do this sort of collaboration, so from the start we had no idea how it would turn out.

"Judging from the latest build we have nothing to worry about though, and so far it looks great,” he said.

“Another interesting aspect is how well it will sell compared to the initial Amnesia launch. Not only is the market a lot bigger now than two years ago, Amnesia is more known.

“The result will be very important to how we plan our future.”

The developer estimated that between 920,000 and 1,360,000 units of The Dark Descent had been sold.

Release for A Machine For Pigs is expected early 2013.
