Microsoft have announced that Max: The Curse of Brotherhood and Halo: Spartan Assault will be the first Xbox One titles that will be free on Xbox One as part of the Games with Gold initiative later this month when the new system update arrives.
On Xbox 360, Dark Souls is currently available for free download with Charlie Murder and Super Street Fighter IV: Arcade Edition hitting on June 16.
There's still no word when the update will hit, but wouldn't it be appropriate if it got pushed out during Microsoft's press conference at E3?
