Microsoft has announced that Halo: Spartan Assault is now available for some Windows Phone 8 users.
I can not unfortunately write most, because in USA Windows Phone 8 users on T-Mobile and AT&T need not apply for 30 days, and until August when Microsoft releases an update, no WP8 user with 512 MB RAM (which in fact may be the majority of WP8 users) will be able to install the game either.
In addition the link provided throws up “This app is not available for your device” error despite my NL 920 being far away from the exclusivity region.
If you are lucky enough to qualify to buy it, you can purchase game for $6.99 here.
It features 25 levels, and users who purchase the app on both Windows 8 and Windows Phone 8 will be able to start the game on one and continue on the other.
