A twin-stick top-down shooter for Windows 8 and Windows Phone 8. Above is the trailer, with action taking place between Halo 3 and Halo 4. According to Microsoft, it “explores the first missions of the Spartan Ops program and dives deeper into the backstory of Human-Covenant wars. Play through the eyes of either Commander Sarah Palmer or Spartan Davis stationed aboard the UNSC Infinity as they fight never-before-seen battles against Covenant forces.”

Developed by 343 Industries in conjunction with Vanguard Games. Releases in July, and of course, there are microtransactions.
