Switches the factions around so that all three races can be played. The balance changes included in the mod address numerous long standing complaints about the original game while the faction swap provides a fresh experience to the gameplay. The mod has been built from scratch with full compatibility on all maps and missions in mind: Any map that worked with the original game will work with this mod. The campaign can also be played either as it was in the original (except with the new balance changes), or using the previously inaccessible Terran units instead.
Update: Version 3 is now out! If you came directly to this page and haven't tried the new version yet, scroll up and click on the Downloads page for the mod. The Reversal mod is a complete balance and faction upgrade for Ground Control 2, fixing numerous balance problems and enabling the Terran faction for play in single and multiplayer modes, including the campaign.
Patch your game to 220.127.116.11. Unzip all files in this .zip folder into your main Ground Control 2 directory. You will need a program such as WinZip or similar. There are three .bat files included - one for each faction combination. Choose which combination you want to play on and run the .bat file for it.
There are more details in the readme included in the .zip and in the content posts here on moddb. Enjoy.
