You can get the map at Lucasfiles!
Coruscant City was originaly a SWBF1 map i converted to SWBF2.
I havn´t found time for some new screenshots so i post a few from the original release but the SWBf2 version looks almost the same
For bigger screenshots visit my website at:
(I want to create a SWBF2 site there soon)
From the Readme:
Made by "Rends"
The Coruscant: City map can be played at both eras in conquest mode and hero assault.
Clone Wars era: A battle blazes above Coruscant, General Grievous has just made a daring abduction of the Chancellor. The expendable CIS droids used as a distraction have remained on the surface to take whatever they can and cuase whatever damage to Republic Forces Possible. The Clones Must eliminate the droid threat.
Galactic Civil War era: Rebel Alliance's Recent Victory at Endor Has left the Empire in Disary. The populous in Coruscant is in an Uprising*. However the Imperials have manage to secure the area near the former senate building, where the Imperial Leaders of Coruscant are plotting to subdue the The Rebel Alliance must take this area from imperial Control, and finally completely overthow Imperial Control of Coruscant.
*As seen at the end of the 1997 and later edition of Return of the Jedi.
Installation: Copy the folder "CO1" (wich contains the Readme, the addme file and the data folder) to your "Star Wars Battlefront II/GameData/AddOn" directory.
