Every month on the 1st, Microsoft offers a handful of games to Xbox One and Xbox 360 for free to Gold subscribers and they have announced their December freebies with oldies and newbies in the mix.
The Xbox One is getting just one game for the entire month with Worms Battlegrounds. Use worms and to battle it out with other worms. Sounds fun.
On December 1st, 360 owners get the crime adventure game The Raven: Legacy of a Master Thief which challenges players with difficult puzzles and a deep story. On the 15th, The Raven is replaced with classic snowboarding game SSX.
