A new teaser trailer for Halo 5: Guardians was aired during last night’s episode of AMC’s The Walking Dead that left Halo fans with more questions than answers.

The teaser trailer is called “Bullet” and offers a number of ominous clues that hints at Master Chief’s ultimate fate. One less-than-obvious clue was the word “Traitor” etched into the bullet that completely shatters Master Chief’s helmet. Who exactly is the traitor is completely unknown at this time? Would the shooter be the one that’s considered the traitor or Master Chief himself? We know this is the second part of a planned trilogy, which tends to mean things are going to get much worse before they get better.

Microsoft will air the first live-action trailer for Halo 5: Guardians during the season finale of The Walking Dead next weekend. In the meantime, check out Bullet below and visit HuntTheTruth and feel free to discuss any other potential clues you may find.
