Summer is upon us, and brings with it more free games courtesy of Xbox Live Gold! Xbox One gamers get the epic tactical strategy game Massive Chalice, from prolific developer Double Fine Productions. They also get Pool Nation FX extended for another month. Xbox 360 players get the rip-roaringly wonderful Just Cause 2, an open-world, stunt-action game that gives new meaning to the term “over the top.” They also get Thief, the recent reboot of the classic action-stealth series, which challenges you to be both subtle and clever. As usual, all games are available only for a limited time, as part of the ongoing Games with Gold program.
