Kane is dead. A new enemy has emerged. It's time to head up the Firestorm task force. Nod's experiments have unknowingly released a horde of cybernetic nightmares upon the world. As GDI and Nod scramble to save themselves, they realize their only salvation lies in the unthinkable. This is a moddable expansion pack for the ever popular C&C: Tiberian Sun game.
The only thing I would say about Firestorm is that it is slightly more balanced and complete version of TS.
