With a recent update for ROTTR (PC), came a little "secret video" in the game files, that shouldn´t be there. In that video we can see that Lara is having problems about Croft Manor and about her heritage!

 The next ROTTR DLC will include Croft Manor! Crystal Dynamics had first told us not to say anything about this but now Crystal left more details about that !

“As some eagle-eyed Rise of the Tomb Raider players have discovered, two placeholder movies were accidentally included in the latest patch. This content was not meant to be released, but now that it is we wanted to respond to the questions we’ve received as a result. The movies are part of a DLC expansion we’re exploring for Rise of the Tomb Raider. Our fans continue to enjoy Rise of the Tomb Raider and its DLC, including Cold Darkness Awakened which released on Tuesday, and we receive many requests for additional story content. We’re always listening to feedback from our fans; especially this year as we celebrate 20 years of the iconic Lara Croft and the Tomb Raider franchise together.”
