Orange Sun formerly known as Orange Touch Up [OTU] enhances Tiberian Sun Firestorm greatly and increases the gameplay possibilities while remaining the original feel of the game. Basically a rebalancing together with new content and lots of spleen.
The first 2 nod missions are done. The third one with the commander that you got to liberate has new starting units and a bit tougher defense but nothing big really. The main mission against Hassan has only a few changes and needs way more work xD
