Some of the assets are from (now bust) developer Free Radical's scrapped sequel. There's also a good chance any famous Star Warrer you care to name has been added as a playable character, based on this list. The mod also includes converted Battlefield 1 maps, which strikes me as a bit like waving a red flag at a monstrously powerful corporate bull that could shut your project down faster than the Falcon can do the Kessel Run. Star Wars: Battlefront 3 Legacy brings in maps from The Galactic Civil War and whatever era of Star War we're currently in.
That's a tad ungenerous, considering how much modders 'El_Fabricio', 'Anakin', 'jedimoose32' and 'Luke Landwalker' have packed into their baby.
It's been playable for years now, but the modders only recently got multiplayer working. Especially so once you remember Star Wars: Battlefront 3 was nearly a thing, and that this mod is chasing what was planned for that - along with much else besides. That makes it far more interesting to anyone who devoted several of their formative years to colonified Battlefront but bounced off its modern incarnation. This is a mod for 2005's Star Wars: Battlefront 2, as opposed to 2017's Star Wars Battlefront 2.
Before we get to the lasers, you must wade with me through the ridiculous murk of stupid video game names.
