Halo: Spartan Assault will start rolling out on consoles later this month, Microsoft has announced. Plus, if you already own the Windows 8 or Windows Phone 8 version, you'll get a discount on the new platform.

The twin-stick shooter will come to Xbox One on December 24 for $14.99. It will feature 1080p resolution and 60 FPS, along with a new cooperative mode, new weapons, and the "Operation Hydra" DLC included. The Xbox 360 version will follow sometime in January 2014. If you've bought one of the other versions, or do it before December 15, getting the Xbox One version will cost $4.99. The announcement didn't mention if that discount will be available for the 360 version as well.
