Huge props to Shaymin for getting matchmaking working, now we know how Star Wars: First Assault would have played. It's very Call of Duty-inspired, which would have marked a stark change in direction had the original plan for this to be the 'first step' to Star Wars Battlefront III come to pass.
Star Wars: First Assault was an internally-developed online multiplayer FPS in the same vein as Call of Duty. It was restricted to Galactic Civil War and featured 8v8 infantry combat that encouraged players to form squads rather than going it alone. LucasArts was to release this via the XBox Live Arcade in Spring 2013, with the game planned to be announced in late 2012. The tech demo is all that has leaked out, and it consists of a single map and incomplete weapons (no E-11 at this stage), however the final game would have had more weapons, as well as maps across Tatooine, Bespin, a Star Destroyer interior, and Kashyyyk. It was content-complete and practically ready to go. It was the first step in LucasArts' three-step plan to Battlefront III - the next game would have included vehicles and Jedi Heroes, and Battlefront III would have added space battles and a campaign. However, First Assault's announcement was cancelled after Disney bought Lucasfilm in 2012. It was be cancelled altogehter when Disney closed down LucasArts.
