SPQR is a total modification for R:TW. The changes encompass all areas of gameplay with added focus on the Roman military machine and the system of recruitment and training of both pre-Marian units and Legions. Special care has been given to the battlefield experience which features the longest battle times of probably any existing mod making tactics an essential component of the game. Definitely not for people accustomed to blitzkrieg tactics both on the battle map and the campaign map.
This is a small addon file that improves the Roman players Urban Cohort with a better model and javelin ability which is better for Town defense. It also includes a small fix for the Egyptian Standard. I personally use this model over the original in my game. But the choice it yours. :-)
