Star Wars Battlefront III Legacy (or: Swbf3: Legacy) is a large-scale conversion mod created for Battlefront II using as many Assets from the cancelled game as possible; including both eras (Clone Wars and GCW), a brand-new HUD+Interface and a few converted maps such as Coruscant and Cato Neimoidia.
Clone Legions will be added to this mod. One is already done: Shocktroopers. Legions/Battalions are only skin changes, not model changes (However due to FRD's addons for the clone commander there actually are some nice matchups when combining different colors here etc.).
Legions/Battalions can be loaded through Fake Console and can even be switched during a match.
