While both the Republic and the Separatists have suffered staggering losses during the Clone Wars, nothing could have prepared them for the battle they face on the desert world of Saleucami.

Now, time and resources have run out, and it's up to a crack team of Jedi, led by Quinlan Vos and Aayla Secura, to infiltrate the Separatist base.
