Alliance are a serie of different mods. On the Star Wars GC, you can play the civil war Empire vs Rebel era + Black Sun and soon the Republic and CIS.
Nawrocki has made new changes on all the ISD and I have edited the weapons and the type of turrets, the ISD MKI has 6 turbolaser turrets + 2 iongun turrets (main turrets with movement), the ISD MKII adds 8 turbolaser turrets with eight guns each turret. The ISD MKIII has better weapons but with the same turrets than the ISD MKII.
Looks a little thick.. texture's nice though
