Orange Sun enhances Tiberian Sun & Firestorm greatly including campaign and increases the gameplay possibilities while remaining the original feel of the game. Basically a rebalancing together with new content and lots of spleen. Now features the Campaign+ modifications.
Laser Cyborgs & Light Tanks fighting the AI
The Laser Cyborg has a different appearance than the usual Cyborg, made by superjoe if I am not mistaken.
The Team Black Tank replaces the old light tank.
