Lieutenant Gregory Adams is a human Alliance engineer. He was hand-picked by Captain David Anderson to serve as the Chief Engineer of the SSV Normandy. Engineer Adams has served on every class of Alliance starships. Prior to being assigned to the Normandy, Adams served on the SSV Tokyo, which he describes as a "good ship" but added that the SSV Tokyo "couldn't hold a candle to the Normandy". Adams becomes very enthusiastic while discussing the Normandy, claiming she is the best ship he has ever served on. Adams will provide Commander Shepard with some background on the ship's IES stealth system and engines.
