Halo 5: Guardians

With a month before the launch of Halo 5: Guardians, Microsoft and 343 are ramping up hints about the story. The latest live-action commercial strikes a somber tone, as the UNSC mourns the loss of a hero.

The Master Chief has been thought dead before. Maybe this time it's for real. Or maybe, just maybe, this has something to do with the ongoing Hunt the Truth radio drama series.

If you'd like a deeper look at the Halo 5 story, we are glad to oblige. You can check out our hands-on impressions with two missions. One features Chief and his Blue Team. The other stars Spartan Locke and Fireteam Osiris.

Halo 5: Guardians is due out on October 27 for Xbox One.
