This is a mod in progress for "Call to Arms" changing the theme into the Star Wars universe with new high quality content, new non-linear RPG gameplay, and many new game mechanics!
The alien (civilians) models seen are just PLACEHOLDERS from LucasArts' Star Wars Jedi Knight: Jedi Academy, those will be replaced.
will there be like steam coming out of holes and rats etc...
nah I think mouse droids are more appropriate :D
On Coruscant there is life (mostly unwanted! and some even quite dangerous) living in the durasteel jungle. They're regular residents of the mid and lower levels. Pretty much like in the real modern cities on Earth.
It would be neat if we see some of it. Although I don't know how doable that is and if it is really worth the resources needed to be spent on them. Still, even if it is done to some degree, it could bring a little more life to the maps.
To the modders:
Most if not all aliens on Coruscant during Imperial Era lived in their own sector (or sector) of the planet (you can call it ghetto) - the Invisible sector: Starwars.wikia.com - it might be a fun idea to play with if you want, since it gives some possibilities.
