Command and Conquer 3: The Forgotten is a mod that aims to bring back and tell the story of a fascinating faction. The Forgotten, featured in Tiberian Sun and Firestorm, are an ever-growing group of individuals who are afflicted with Tiberium-based illnesses. Detested, marginalized, and oppressed by the three superpowers, The Forgotten have begun to rally against GDI, Nod, and the Scrin. Since their story is not featured in C&C 3, the mod aims to tell it in a compelling fashion, through a deep singleplayer campaign, unique faction composition, and engaging gameplay. Prior to its announcement, the mod was in quiet development by many of the developers behind C&C All Stars, lending the project a rich and experienced perspective.
