Amnesia: A Machine For Pigs Discussion Topic Part 2

[Paddy™]

You're right Statyk, in the Q&A Dan was asked about another Amnesia sequel and this was his answer:

We're already onto the next game It'll have to be someone else next time

It's probably safe to assume this goes for DLC/add-ons too. Frictional probably wouldn't have the time to do it themselves because of the Super Secret Project, which is their primary focus. It was this secret project and its demands on the team's time which made it desirable to bring in The Chinese Room to develop AAMFP in the first place. Unless they commission another third-party team to make some DLC I doubt it'll happen. Although it would sure be interesting if they did!
