Decades on, the alien crystal called tiberium has poisoned much of the planet, leaving whole regions dead and mutated. Into that ruin the Brotherhood of NOD stirs from dormancy and opens a surprise war on the Global Defense Initiative. Tiberian Sun is the long-awaited sequel to the 1995 game that helped define real-time strategy, and it looks the part: walking mech titans, ion storms that scramble the battlefield, deformable terrain. You pick GDI order or NOD zealotry, harvest the very poison choking the world, and grind toward the other side's collapse.
