Microsoft today announced the free  that will be available to Xbox Live Gold members on Xbox 360 and Xbox One in May.




After a month in which it offered twice as many free games as usual, May takes us back to the usual arrangement: two Xbox One games (one of which, Pool Nation FX, is a carryover from April) and two new Xbox 360 games.
As usual, the Xbox One games will be free all month, while the Xbox 360 games will each be available for half the month. The new One game, CastleStorm: Definitive Edition, and the first 360 game, Mafia II, should be available starting this Friday, May 1.
