This is a modified map pack campaign for RA3 Reloaded version 1.2 for those players who are stuck in SP campaign missions with low power under a vehicle power requirement.
All you have to do is to extract the file in your C:\Program Files\Electronic Arts\Red Alert 3\Data directory. A backup spare file (MapsCampaign.big) is highly recommended before overwriting the file. DO NOT DOWNLOAD THIS FILE UNDER DESURA!!
In this map pack, most SP campaign missions have added a power plant for each player (including co-op) to simplify the process going through missions.
