Microsoft’s expansive marketing campaign for Halo 5: Guardians begins now. Watch the helmet-shattering teaser trailer above and at the end you’ll notice the hashtag #HuntTheTruth. Shortly after the televised teaser launch, MSFT opened up a “Hunt the Truth” Tumbler that further explores the mystery behind the shrouded plot of the upcoming game. Fictional journalist and war photographer Benjamin Giraud hosts a weekly podcast that promises an in-depth profile of the Master Chief with an aim to uncover the truth behind his origins and motives. Fans of the Xbox franchise (myself included) are going to eat this up.

Halo 5: Guardians is expected to release this fall on Xbox One.

Update (3/29): Microsoft unleashed two extended trailers for Halo 5: Guardians tonight during the season finale of The Walking Dead on AMC. The first features Spartan Locke threatening Master Chief: “All hail the conquering hero. The one who was supposed to save us all. But now I must save us from you.” The second spot reverses the roles, with Master Chief pointing his weapon and saying, “You’ve completed your mission, Spartan Locke.” What’s happening?! See for yourself after the break. Also confirmed: the next Halo comes exclusively to Xbox One on October 27.
