Halo 5: Guardians continues the story of the Master Chief, and introduces a brand new central character to the Halo universe – Spartan Locke.  Peace is shattered when colony worlds are unexpectedly attacked.  And when humanity’s greatest hero goes missing, Spartan Locke is tasked with hunting the Master Chief and solving a mystery that threatens the entire galaxy.

Experience the most dramatic Halo story to date in a four-player cooperative epic that spans three worlds. Challenge friends and rivals in new multiplayer modes: Warzone, massive 24-player battles, and Arena, pure 4-versus-4 competitive combat.

We haven't seen a Halo game (apart from Halo: Spartan Assault and Halo: Spartan Strike) on PC in almost a decade, but 343 Industries’ franchise director, Frank O’Connor has revealed in a recent interview that:

"You know, Microsoft has made a huge commitment trying sort of. I think normalize the Windows experience across multiple platforms. You see the elements of Windows 10 are going to appear in Xbox and Cortana and stuff like that.. There is plenty of chance that Halo 5 could appear on the PC, nothing to announce at this point, but it’s absolutely within the bounds of reason. You know, we developed the game on an Intel platform. It wouldn’t be the hardest thing in the world to move it to PC and take advantage of PC stuff. But nothing I announce today on this chat."
