What is the name of the Assassin's Creed Origins expansion about the Egyptian afterlife?

The Assassin's Creed Origins expansion about the Egyptian afterlife is The Curse of the Pharaohs.

Released in 2018, the expansion continues the story of Bayek of Siwa and sends him to the Valley of the Kings region. Its supernatural plot involves ancient pharaohs and disturbances connected with Egyptian beliefs about the afterlife. The game creates playable afterlife realms inspired by mythology, allowing Bayek to confront powerful historical figures in fantastical environments.

The expansion is separate from The Hidden Ones, which is the first major downloadable content pack for Origins and continues the historical formation of the Hidden Ones. Dead Kings belongs to Assassin's Creed Unity, while The Fate of Atlantis is an expansion for Assassin's Creed Odyssey.

The Curse of the Pharaohs also raises the level cap and adds new abilities, gear and areas. It therefore combines a mythological scenario with the role-playing systems introduced by Origins.
