Unzip all the files into your Orpheriun 3 tc folder.

Make shure the Default.txt and metal.txt go into a folder called AI.  If they are in your main directory, make a new folder called AI and drag the 2 files into that folder.

Enjoy the game.

The ai is modified so that the Rhyoss and Scr'ee will not build anything stronger then basic fighters and frigates.  This way you can have a ballanced game agenst them when playing as the Zahn.  If you want to play agenst the normal AI, just rename the AI folder.
