Here is the announcement for doubles attack in case you don’t go to B.net anymore.
Here in the aftermath,
On the verge of extinction,
Where fear finds purchase,
Only two will stand fast,
Defiant until the end.
Doubles Attack: Unearthed Edition is now live!
Available for a limited time in the DLC playlist category, play Doubles Attack exclusively on the Firefight map Unearthed from the Defiant Map Pack.
