Mass Effect 3: Citadel

Mass Effect 3: Citadel — the player's main base of operations — it is a personal apartment that Shepard lent to Admiral Anderson, a war hero and Shepard's mentor who is currently on Earth. From the apartment, the player can customize furniture, initiate quests, interact with non-player characters, and then access other areas of the Citadel. The first half of the package is story-oriented and generally alternates gameplay between apartment and third-person shooter action around the Citadel, but also includes a casino infiltration mission that requires some stealth elements. The story culminates in a boss battle aboard the Normandy against a Shepard clone whose combat tactics and character class are pre-selected to match those of the player.
