Not one, but two new trailers made their debut last night for for Halo 5: Guardians. Both trailers feature the legendary Master Chief against the UNSC’s top manhunter: Spartan Locke. The game is scheduled to launch worldwide 27th October, only on Xbox One.

The first one, titled All Hail, seen above, highlights Spartan Locke drawing down on the compromised Master Chief, questioning his legacy and motives.

While the second one, titled The Cost, shows the Master Chief with the upper hand over an injured Spartan Locke, showing the true price of being a hero.

Which version is true? The hunt is on to discover the truth!

We wanted Halo 5: Guardians to be the game that pays off the epic promise of the Halo universe in scope and scale and drama,” said Bonnie Ross, Head of 343 Industries. “We want to amaze players with the sheer size of the worlds and battles they’ll experience, even as they question everything they thought they knew about its heroes, marvels and mysteries. #HunttheTruth is only the beginning and we can’t wait to debut the game to Xbox fans around the world at E3 this June.
