No Plans to offer the title for Windows Vista at this time.

After an unnamed source provided Angry Pixel with information regarding a PC version of Halo Wars, Microsoft has responded denying any existence of a PC version of the "bottom up" Xbox 360 RTS.

"Halo Wars is being developed from the bottom up for the Xbox 360 and its control scheme to ensure that we deliver a groundbreaking console RTS experience," a Microsoft spokesperson told IGN.

"Given that, we have no plans to develop Halo Wars for Windows Vista at this time."

Angry Pixel had also suggested Halo Wars would feature cross-platform multiplayer between the Xbox 360 and PC, much like Microsoft's Shadowrun.

Given the close relationship the RTS genre has with the PC it wouldn't surprise anyone to see a PC version of Halo Wars at some point down the line, but for now Microsoft insists the game is only for Xbox 360.
