Halo: Spartan Assault's story fills in the gap between the events of Halo 3 and Halo 4. It provides a more in-depth look into what happened during the Human-Covenant Wars. Unfortunately, not everyone has access to Windows 8 or a Windows 8 mobile device just yet, so for all of the Halo junkies out there who haven't upgraded yet, we've done all of the work for you. For those of you who are going to play Spartan Assault, this is your SPOILER WARNING. The video above contains all of the in-game cinematics.
