We're coming into the last month of the year, which means we're moving into the last batch of free games on both consoles for 2015 too. As is usually the case, Xbox has blinked first and revealed its lineup.
The Incredible Adventures of Van Helsing will be free on Xbox One all month long, while Thief will be around from December 16th to January 15th. On the Xbox 360, Sacred 3 will be available all month with Castlestorm being the mid-month title there. Operation Flashpoint: Dragon Rising will also be available from December 16-31st.
I wouldn't say there is anything too strong there, but hey, free games are free games. You can't complain too much.
