GameOver heeft een review van Firestorm gemaakt. De reviewer verwachte een hoop van C&C Tiberian Sun, maar vond de game zwaar tegenvallen. De addon Firestorm scoort dan ook maar 68%.The terrain has had some minor enhancements also. In multiplayer mode, certain maps have Ion Storms; random Lighting will occur for about 2 minutes causing minor damage. There were also some new Tiberium plants that added some beauty to the map but that's about it. This add-on didn't add much, making it an undesirable game to purchase. If you were a C&C fan like me and stillhad some hope that Westwood would make up for it in the add-on, then prepare to be let down once more.
