Microsoft has revealed the four free Xbox games it will offer to paid Xbox Live Gold members for free in September as part of the Games with Gold program. It includes Tomb Raider: Definitive Edition and The Deer God for the Xbox One and Battlestations: Pacific and Crysis 3 for the Xbox 360.
Xbox Live is Microsoft's digital media delivery service perhaps best known for its connection to online gaming on the Xbox 360 and now the Xbox One. Originally it actually launched back in 2002, the days of the original Xbox, with updated versions coming in 2005 with the Xbox 360 and again in 2013 with the Xbox One.
Xbox Live has also extended beyond the Xbox consoles, with an integration in Windows gaming and Windows Phone. With the forthcoming launch of Windows 10, Xbox Live will grow again.
