Star Wars: First Assault, an unannounced game from LucasArts, was a multiplayer shooter designed to test interest in Battlefront 3, Kotaku reports. First Assault was going to host a closed beta in September, with a launch scheduled for this spring, but when Disney bought LucasFilm in September the project was put on hold, the website says.
The September beta timeline agrees with a leaked image promoting First Assault on XBLA, uncovered in early October.
Kotaku cites someone "no longer familiar with the goings-on" at LucasArts, but with knowledge of the project for the following information: First Assault was a downloadable, multiplayer shooter supporting up to 16 players in various Star Wars worlds, and was supposed to gauge interest in a rebuilt Battlefront game. After years of being passed around studios, having been nearly completed and canceled, starting Battlefront 3 from scratch would probably be a good call.
