Well, this really is lovely.
I reported a few days back that it looked like The Wolf Among Us was going to be part of Games with Gold, but what I didn't know was that it would also be joined by another great game. Sunset Overdrive (April 16-May 15) is going to be given away to Xbox Live subscribers on Xbox One in April, alongside Telltale's series (April 1-30). On Xbox 360, Dead Space (April 1-15) and Saints Row 4 (April 16-30) will be offered too.
That's a great month of game. If you haven't played Sunset Overdrive, I fully encourage you to. It's pretty excellent, and there isn't much like it being made these days. The other titles are all great in their own right too, so have at it.
