Let's say I wan't to add a second vader to the GALACTIC CONQUEST, Like a "Vader2", how can I do that?

well....You can try putting Darth_team in the campaign twice.  That's a surefire way of putting him in.

 

Just open up campaigns_singleplayer and add this line somewhere twice:

 

Empire, Coruscant, Darth_Team

 

You can use any other planet name and what-not.  Hope this helped.

Yep Thanks!, so, if a have another vader (Different name, etc), I just have to add that line?

Your welcome.  And yes, just add the line.

ok, it worke, I have a new unit called doom giver(Darth Vader), but the name and tooltip that I created just appears in the Galactic Mode, in the tactical mode it appears as a normal vader, how can I chage this?

You'll have to create a new named hero in the namedhero.xml or whatever its called.
