A new Xbox One advert released today isn’t as straightforward as it appears.

The trailer has a couple of pretty conspicuous ‘glitches’ throughout, and members of NeoGAF wasted no time in breaking it down.

The first item of interest is the screen from the hunt the signal site, which displays an error message when accessed from a PC, but when accessed from a phone, it displays a countdown (currently at the 120 hour mark). This is reminiscent of the teaser site that popped up earlier this year.

Digging further, NeoGAF have discovered that the glitches actually relate to a competition – an Xbox One advertisement glitchHalo contest. Teams of 4 can sign up here and the winning team “will be invited to provide a photograph of themselves which will be used to create characters in their likeness to appear in the game Halo 5”.

The terms and conditions list the following minimum requirements needed to complete the Halo: Hunt the Signal experience, including smartphone capabilities:

Video Element

Canvas

Gyroscope (mobile)

Compass (mobile)

Geolocation (mobile)

Websockets

The competition is only open to UK and US residents. The timer could be counting down to the start of the competition, to give participants enough time to form a team and prepare themselves for who knows what. But that’s just a guess at this stage.
