After months upon months with seemingly no hope for a new Zero Hour patch, EA has released patch v1.03 today!
Patch 1.03 for Zero Hour can be downloaded from EA's public FTP here
Electronic Arts reportedly relied heavily on the German ACETON Balance Mod
for this patch, which includes numerous improvements and bug fixes. Most noteworthy is the fix of the unfinished building exploit, commonly referred to as the "SCUD Bug". A number of balance issues were also addressed. Patch 1.03 changes the prices of a few units, and the Generals World Generals Profiles
pages have been updated accordingly.
