Microsoft mouthpiece Major Nelson has announced September’s lineup of Xbox Games with Gold, with Lego Star Wars III: The Clone Wars leading the charge.

The blocky sci-fi actioner will be up for grabs from September 1 -15, and will be joined by Prison Architect on the same day. Unlike Star Wars however, Prison Architect will be available until September 30.

Livelock and Sega Vintage Collection: Monster World will then be added to Xbox Games with Gold on September 16, and will remain there until October 15 and September 30, respectively. 

Obviously, Lego Star Wars III: The Clone Wars and Monster World are Xbox 360 games, which can be played via Xbox One’s backwards compatibility feature. 

Don’t forget that there’s still time to grab a couple of last month’s Xbox Games with Gold titles if you haven’t already done so.
