'Rainbow Six Siege' DLC news: First DLC 'Operation Black Ice' now available; frozen yacht map, Frost and Buck operators confirmed

The much awaited first of the four downloadable contents for Ubisoft game, dubbed as "Rainbow Six Siege: Operation Black Ice," is now available to download for free, as announced by the game publisher on their Steam page.
"Currently moored in Baffin Bay, this luxurious yacht has struck an iceberg and has been breached," Ubisoft wrote for the map's description. "As part of Team Rainbow, you're being sent in to help secure the stranded vessel, as an unidentified submarine has been seen docked close by."
Aside from the map setting, the official post from the publisher has also confirmed the two rumored operators: Frost and Buck. As it turned out, the leaked details that were spotted circulating online later last January were in fact accurate, which included the skills that the two can use, specifically the "Welcome Mat" trap for Frost and the "Skeleton Key" under-barrel shotgun for Buck, which is an add-on to his primary used weapon. A new set of Seasonal Weapon Skins have also been included in the "Operation Black Ice" DLC, as can be seen on the content's official page on the game's website.
Lastly on the newly added features, the "Rainbow Six Siege: Operation Black Ice" DLC will also introduce the Spectator Camera. Ubisoft explains that, "The Spectator Camera allows players to create custom 5v5 multiplayer games, with an 11th player observing the match in real time."
This new feature is also said to introduce a new kind of perspective when in spectator mode, which is called Tactical View. "This view allows players to select and follow individual players, or use it's 'free-cam' to observe the map as a whole," Ubisoft said.
In addition to these, Ubisoft has also released a new patch for "Rainbow Six Siege," which contains many bug fixes and improvements in the gameplay aspect, User Interface (UI), Online aspect, and possibly even more.
