Destiny 2: Shadowkeep

Destiny 2: Shadowkeep is an expansion for a multiplayer first-person shooter set in an open sci-fi world. Former guardian Eris Morn was tormented by visions of her past and returned, unleashing something terrible. An incredible power has been hiding under the surface of the Moon for many years, and even she will not be able to control it. You have to go deep into the enemy stronghold and, together with Morn, destroy the enemies before they reach humanity and throw it back into the era of darkness.

The add-on requires the original version of Destiny 2.
