Seattle Sounders FC is prepping for a Halo 5-related announcement tomorrow.

xboxjersey1The soccer club today posted a short video and tweet teasing a “huge announcement” being made on Tuesday.

The tweet reads: “Pitch Black gets an upgrade for #SEAvLA. See it tomorrow. #Halo5SFC.” Pitch Black refers to the team’s alternative black jersey kit that it unveiled last year.

For the past six years, the Sounders have sported “Xbox” on their jerseys since the club entered Major League Soccer in 2009 as part of a sponsorship deal with Microsoft.

The original jerseys featured “Xbox 360,” but Microsoft has gone with the simple “Xbox” ever since. The two companies inked a 2-year extension this past December.

However, this is the first time Microsoft is using Halo-related branding with the Sounders, so it will be interesting to see what exactly the club announces on Tuesday.

Halo 5 is set for release on Oct. 27 and will be the third Halo installment from Kirkland-based and Microsoft-owned 343 Industries, which also developed Halo 4 and Halo: The Master Chief Collection after taking over the franchise from Bungie in 2007.

Halo 5 will be exclusive to Xbox One, likely forcing Xbox 360 owners to upgrade to the latest Microsoft console. Microsoft started taking pre-orders for the game in December.

We’ve reached out to the Sounders and will update this story as we learn more.
