halospartanassaultHalo will makes its Xbox One debut on Dec. 24, as Microsoft announced today that Halo: Spartan Assault will be available for $14.99 on the new console in time for Christmas.

Spartan Assault is not a classic first-person shooter in the mold of traditional Halo games. Instead, it’s a top-down shooter that gives a third-person perspective as the heroes of the United Nations Space Command battle Covenant forces.

The game is already available on Windows 8 and Windows Phone. Those who purchased Spartan Assault on those platforms before Dec. 15 can buy the Xbox One version for $4.99.

Spartan Assault on the Xbox One features a couple new features, including an online co-op multiplayer mode, along with new weapons and achievements. The game will also debut on Xbox 360 next month.

Meanwhile, Microsoft is already taking pre-orders for the highly-anticipated next installment in the Halo series, which was announced at E3 this year and will debut on Xbox One in 2014. Kotaku had an interesting piece here about how Microsoft considered launching Halo 4 with the Xbox One, but ultimately decided to release it last year for Xbox 360.
