Posted through the Xbox news channel, May’s Games with Gold offering has been announced, ushering in three new games for Xbox Live Gold subscribers to download for free.

The first – which is available all month – is CastleStorm: Definitive Edition on Xbox One. The game is a genre mash-up that combines medieval warfare with 2D physics-based destruction. Pool Nation FX remains as the other free Xbox One game for those that still haven’t picked it up.

On the Xbox 360 side of things, from the 1st of May to the 15th, Mafia 2 – the sequel to one of my favorite games of all time is available for free. From the 16th to the 31st, F1 2013 rounds out the selection.

CastleStorm and Mafia 2 are my personal picks this month, as I was a big fan of the latter and I’m quite the fan of medieval warfare. To grab these games for free, just remember you’ll need to be an Xbox Live Gold member.
