Because we all know that the red Fal'shia colour scheme sucks, this mod changes the Tau in the single player campaign for Dawn of War: Soulstorm to the T'au colour scheme (the same one used in the campaign for Dawn of War: Dark Crusade).
The mod changes all unit textures and UI icons to the T'au colours. All text references to Fal'shia are also changed to T'au. Note though that the mod does not change the Tau's colour scheme in the movies that begin and end the campaign.
Before installing, ensure that you have the most recent version of the Soulstorm Bugfix mod installed first. It can be downloaded from here: Moddb.com
To install this mod, extract the "ss_campaign_tau_sept" folder and "ss_campaign_tau_sept.module" file from the zip folder into your main Soulstorm folder. The mod can then be selected from the Game Manager on the Soulstorm main menu.
