The download includes two versions: one for the Brave New World Mod Ver.3.2 and one for the standard rule set with the Unofficial 1.4 Patch.
If you have already downloaded the initial version and only plan to play with BNW3.2, you do not need to download this file as the changes are minor.
The gods have always been enamored with the balance between good and evil. Rather than a straight up battle, who would have the edge when patience and planning are the key?
To answer the question, they created a world split in two. An impenetrable barrier separates the two halves---for 70 days. Then the barrier will be breached and the armies of good and evil can have it out. Who will be best prepared when the barrier is breached?
So, you have 70 days to build up your armies and the heroes and infrastructure needed to support them. Be warned that, although in the beginning you will be protected from your principle adversary, there will be wandering independents that will attack you if they think they can win. They will also capture anything that is not well guarded.
The scenario features Jack's High Speed Roads that are three times faster than normal roads. Just make sure to read the warning signs.
