Star Wars The Old Republic: Ultimate War is a mod for Empire at War: Forces of Corruption. It features most of the Old Republic period in a massive compilation of conflicts.
NOTE!
I do not take credit for these models, they are from the Star Wars: The Old Republic game and are property of Bioware, EA Games, and Lucasarts.
Here's a model of the Zakuul Walker. It is based on the Republic and Imperial Lance Walkers, and will operate along the same lines.
OMG wow amazing
