Crossplay

Is Command & Conquer: Tiberian Sun - Firestorm crossplay?

Command & Conquer: Tiberian Sun - Firestorm is only released on one platform, so there is nothing to cross-play with.

Firestorm is the official Expansion pack for Command & Conquer: Tiberian Sun and was released in March 2000 by Westwood Studios. Whether or not the information about the death of NOD leader Kane is true, it appears that a new menace is developing; this force will require an alliance between the Global Defense Initiative and the Brotherhood of NOD. There are 18 new single-player missions and 15 multiplayer battles to keep you busy, and more than 30 minutes of live-action video to move the story along. Fight thousands of opponents for control of 30 territories in online play.
