If you want your Halo fix for a more tactical top down shooter experience then look no further than your Windows 8 devices. Yes, this means any computer with Windows 8, your Surface, etc. Also you can get Halo: Spartan Assault for Windows Phone 8 if you’re so inclined.
I will mention that while Halo: Spartan Assault is out for both Windows 8 and Windows Phone 8 if for some reason you want to play it on both devices you will have to buy it separately. With that being said, Halo Spartan Assault is a mere $6.99 and is well worth the price as you are getting a high quality game with a lot of updates already planned. If you do buy Halo Spartan Assault for both devices you can sync your progress which is pretty awesome. If you are only going to get Halo Spartan Assault on one device, which should you choose though? General Windows 8 offers keyboard support, larger touch screens, and future Xbox 360 controller support which puts it ahead of Windows Phone 8 features wise. So go out and get this awesome game now!
