a week ago or so, I released the "Second Sides Mod" 1.0.1 on filefront. Now I'm making a large update to it. what should I add?
What I've added
1 new Stormtrooper Legion: TFU 501st
edited campaign
CW:
Battle of Naboo
Theed Rebellion
Battle of Geonosis
Battle of Kamino Cloning Facility
Rhen Var: Harbor
Mygeeto: Amongst the ruins (by scum/strike)
Kashyyyk
GCW
Naboo: Imperial Diplomacy
Mustafar: Tying up loose ends
Mos Eisley: the search for the droids
The Wookiee Rebellion: Wookiees vs. Stormies, play as Wookiees led by Galen Marek
The Fall of Yavin IV (same as shipped)
Hoth
Cloud City
Bespin Platforms
Endor

Maybe make an option or map where you can play as the clones betraying the wookies... something from episode III.

What do you mean by 'new campaign' - as in accessible via the Historical Campaign menu?

How did you do that?

If you are adding a TFU side, go all out with it and include the Navy troopers too, and a Battle of Kashyyyk where we have to fight the Wookies to get to Kento marek (Starkiller's Father)

Yes its the historical campaign menu.
I did the shipped maps by copying over luas from one to the other.
for the scum/strike maps as a part, I put the actual myg1.lvl (the map) in the RHN (rhen var folder), and edited the historical lua to read myg1.lvl instead of rhn1.lvl (rhen var).
Instant Action is the same.

say, where could I find the Imperial Navy Commando besides filefront as the d/L page for it is broken.

I have the TFU-like Kashhyyyk as both, the campaign and as a mission fix for Majin Revan's Kashyyyk: Shores 3.0 (because that map is awesome and has vehicles), i still need to make sides.
