This month's Games with Gold for Xbox have been announced. On Xbox One Hand of Fate will be free for the month of February, and from February 16 - March 15 Gold subscribers will also be able to download stealth title Styx: Master of Shadows.
Meanwhile, on Xbox 360, from Feb 1 - Feb 15 you can download Sacred Citadel, and in the second half of the month you can chainsaw the hell out of aliens in Gears of War 2. Of course, thanks to backward compatibility, both of these games also work on Xbox One too.
