Halo: Spartan Assault finally hit the Windows Phone Store on late Thursday. For 30 days inside the U.S., it is an exclusive
for Verizon branded Windows Phone models. Outside the U.S., there might not be a carrier exclusive but some Windows Phone owners are apparently having a problem downloading the game because of a problem. A tweet from Microsoft's Joe Belfiore let those who could not successfully download the game, know that Microsoft is aware of the situation and is working on correcting the problem.
Halo: Spartan Assault costs the equivalent of $6.99 and requires that you own a high-memory
Windows Phone model. After the initial $6.99, you have the option of purchasing temporary weapon upgrades. For these, you need to buy additional credits which are available for as low as $2.99 (500 credits) to as high as $39.99 (10,000 credits). But it is all for naught if you can't download the game. Hopefully, Microsoft makes the necessary adjustments soon. Belfiore's tweet suggests that it won't be longer than a day or so.
