May is coming, and Microsoft has let slip the Games with Gold offerings for the month a bit early this time. As always, next month will bring four new games free for Xbox Live Gold members--two on Xbox One and two on Xbox 360. The first will be coming on Tuesday, May 1.

First on Xbox One, you can ring in America's past-time with Super Mega Baseball 2. That will be free throughout the entire month. Then, starting on May 16, Xbox One will also receive Metal Gear Solid 5: The Phantom Pain, the last game in the series helmed by creator Hideo Kojima.
