Microsoft is inviting everyone to their summer barbecue with another weekend of Free Play Days. For the next four days all Xbox Live members can play online and enjoy the benefits of Gold for free. Anyone who logs on this weekend will also have access to two multiplayer titles: Bethesda’s spinoff MMO The Elder Scrolls Online: Tamriel Unlimited and arcade racer OnRush. Both games can be freely downloaded and played to your heart’s content, but only through the duration of the event. Free Play Days will be running from now until 11:59 p.m. PDT on August 12, so be sure to enjoy a long weekend of free online gaming while it lasts.
