Age of Darkness is a mod set in the historical period spanning the two world wars of the 20th century, revolving around the struggle between the forces of liberty, socialism and reaction.
One of the problems associated with Rise of Nations is the fact that you can only utilise up to 3 working turrets and 4 working nodes for ammunition sprites. I've been at work, trying to create a proper rig (with animation) that would go around this problem.
