Halo Spartan Assault is Microsoft’s first real attempt at bringing their franchised games to WP, and it’s actually quite good. Of course it’s also carried a slightly elevated price tag ($6.99 iirc) which might have turned some people away. Thankfully though Halso Spartan Assault is now the deal of the week on both Windows 8/RT as well as WP, meaning you can grab it for a much nicer $1.99; which is a pretty awesome deal.
