After teasing DLC for season two of Rainbow Six: Siege earlier this month, Ubisoft announced a release date for Operation Dust Line on Twitter. "We’re proud to announce that our next DLC, Operation Dust Line, will be released on May 11th. More info soon."
Soon means soon: Ubisoft will be showing off Operation Dust Line during a livestream set for this Saturday, May 7. A brief teaser is also available
In the meantime, we can review what we already know about the forthcoming expansion pack. There will be two new characters: Valkyrie, a Defender who wields sticky cameras and a SPAS-12 shotgun; and Blackbeard, an Attacker type who mounts a shield to his weapon and packs a Desert Eagle.
