Microsoft has announced May’s Games with Gold for Xbox Live Gold subscribers.
A post on the Xbox Wire reveals that CastleStorm: Definitive Edition will be available for Xbox One owners, as well as Pool Nation FX, which was available in April. Xbox 360 players will get Mafia II from May 1st until the 16th when it will be replaced by F1 2013 for the remainder of the month.
As these games become free, April’s offerings will revert to paid status. So get April’s games while you still have the chance.
