Update 2: The Windows Phone version is now also live in the Windows Phone Store.

Update: Halo: Spartan Strike is now out for Windows 8.1 in the Windows Store, but there's still no sign of the Windows Phone version.

Original story: After several months of waiting, Microsoft has finally released the top-down sci-fi shooter sequel Halo: Spartan Strike. The bad news is that the title, from developer Vanguard Games, is available first on iOS devices, ahead of its promised release for Windows Phone, Windows 8.1 and Steam platforms.
