Electronic Arts CFO Blake Jorgensen made a statement back in November that one of the reasons they go with different approach with their microtransactions such as actual boosts that give players advantages in multiplayer, instead of just cosmetic options is because no one would want a Pink Darth Vader.
A modder by the name of Destauch has shared a Darth Vader in Pink mod over on Nexus Mods and players can download it now. You don’t get any advantage or abilities with it than what is advertised: Darth Vader, but in pink.
The mod only works with the PC version of Star Wars Battlefront 2, and you will need the Frosty Mod Manager to install it.
