Obsession thrives on the dramatic stories written during the Victorian era: shocking revelations, distressing tragedies, unheard-of secrets, and family scandals. Facing the twists and turns of these stories is your tactical challenge in Obsession.

The Upstairs, Downstairs expansion offers you new opportunities to influence your fate. Of course, the new gameplay mechanics are once again integrated into the theme—especially regarding the abilities of the new household staff.

In addition to the four new servants, you will encounter the new Howard family, which already has a cook at the start of the game. With the new family, you can now play Obsession with five players or even six when combined with the Wessex expansion.

This expansion cannot be played without the base game Obsession.
