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.
The Relentless battlegroup has a new ship, the Wombat Escort Frigate. The model has been made by Jedi_Consulor and @Tony@, skin as many other models made by Nawrocki over a previous Evillejedi design. On the screenshots you can see the Relentless made originally by Mayor A Payne and one ISD MKII edited for to be a escort ship. I have added special turrets with 8 barrels each of them. Of course the skins are from Nawrocki. The Coruscant texture is a special work from Burnstrobe. Now the Relentless battlegroup is very completed.
