"Blood Ties" is a free DLC expansion for Rise of the Tomb Raider. Lara must explore the Croft Manor to find documents and objects that might shed light on Lara's family background and undo the claims of her uncle Atlas. Atlas despised Lara's father, the late Lord Richard Croft. Atlas claims he's the true owner of Croft Manor, and Lara is to vacate the property and hand it over to Atlas. Lara must find the key objects and documents to prove her uncle's claims invalid. The gameplay consists of mostly walking around the Manor, almost like a Tomb Raider version of "Gone Home". You'll listen to lots of audio clips, and peer at various objects as you explore the Manor on a dark and stormy night.
