Faith Connors from Mirror's Edge and Natasha Volkova from Command & Conquer: Red Alert 3 were planned to appear in the game as guest characters, but were both scrapped for unknown reasons. Despite this, Faith makes a cameo as a picture on the wall of Gal Force 4's base, and Natasha has leftover files in the game, suggesting that she was cut late in development. Additionally, artwork exists of an old man character who would have appeared in the game as a member of Crescent Moon, but was also scrapped.
