Halo: Spartan Assault will arrive on Xbox One Dec. 24 for $14.99, Microsoft announced today.
The Xbox 360 version, which was previously slated for a December release, will follow in January 2014.
The top-down, third-person shooter was originally released for Windows 8 PCs, phones and tablets and will make its way to Microsoft's next-gen console on Christmas Eve. Those who've purchased the PC or Windows Phone 8 versions before Dec. 15 can buy the Xbox One version for $4.99.
The console ports will include new achievements, which Microsoft detailed last month.
