Command and Conquer: Tiberian Sun + Firestorm

Tiberian Sun features three factions, each with its unique strengths and tactics; the Global Defense Initiative (GDI), the Brotherhood of Nod (Nod), and The Forgotten (non-playable, neutral faction of mutated humans who have been physically and mentally affected by the Tiberium toxins). The storyline follows the continuing struggle between the GDI and Nod, the latter of which is ready to launch a new set of surprise sneak attacks in a desperate attempt to wipe the Global Defense Initiative off the face of the Earth.
