The top-down shooter that started on the moribund Windows phone platform and Windows 8 in July, went to both Xbox platforms around the holidays, and is finally coming to Valve's digital distribution platform.

At GDC, Microsoft Studios head Phil Spencer promised that Microsoft would be reinvesting in the PC space, which it has largely neglected in recent years. Today the company announced that 343 Industries/Vanguard Entertainment-developed Halo: Spartan Assault is coming to Steam on April 4. When Kyle reviewed the Windows/phone/tablet version last year, he largely enjoyed it. This version includes controller support and Steam achievements, so if you haven't played it yet now is as good a time as any. 

You can try it for the low cost of $4.99 (other platform prices range from $6.99 to $9.99 currently).
