There's nothing like a little thematic synergy, so Xbox's Games with Gold line-up for May pays tribute to the unofficial Star Wars Day, May 4. Both of the Xbox 360 games for the month, also playable on Xbox One, are set in a galaxy far, far away. First comes Star Wars: The Force Unleashed 2 from May 1-15, followed by Lego Star Wars: The Complete Saga on May 16-31.
The two Xbox One exclusives for the month are less themed but pretty nice offerings. Giana Sisters: Twisted Dreams - Director's Cut will run for the full month of May, and Lara Croft and the Temple of Osiris will be available from May 16 to June 15.
As always, Games with Gold is available to all Gold subscribers. For the 360 games, once you've obtained a game through the service, it's yours forever even if you let your Gold subscription lapse.
