Today Microsoft officially announced that Halo: Spartan Assault is coming to Xbox One and Xbox 360 in December. It will be available as a downloadable title.
This console version of Halo: Spartan Assault includes Operation Hydra, which was free DLC for Windows 8 and Windows Phone 8. The biggest addition are all new co-op missions that put players up against The Flood, armed with new weapons, abilities and upgrades. Of course, there will be new Achievements as well.
