Tomorrow, the cycle will be complete. Halo: Spartan Assault started as an odd twin-stick spin-off for touch-based Windows 8 and Windows Phone devices. However, it's since spread to Xbox One. Tomorrow, it'll complete its journey across Microsoft products by landing on Zune Xbox 360.

Microsoft sort of attempts Cross-Buy support with Spartan Ops, giving a discount to players that purchased either the Windows 8 or Windows Phone version of the game before December 15th. Eligible players will be able to buy the Xbox 360 version at a discount: $4.99.
