"Call of Duty: Black Ops rewards you with killstreaks, but what do they all look like? Here's a handy video guide that will show the best rewards you can get if you kill people without dying in the CoD: BO multiplayer. Between remote control cars, SAM missile turrets, and attack dogs, there's a lot to choose from. Personally, I was hoping for flying piranhas, but that SR-71 Blackbird killstreak is pretty darn sweet. Get streaking now."

The video on Black Ops 1 shows some separate rooms, assets, and other features which exist outside of the boundary of the game.
From DownSights: "Black Ops is not Black Ops without Nuketown. Following the tradition of releasing Nuketown for Black Ops games, the new Black Ops Cold War game also offers a revamped Nuketown called Nuketown '84.
Nuketown '84 has the same dimensions and map layout except for the aesthetics. The map's aesthetics have changed to fit the 80s theme, with destroyed buildings and graffiti-filled walls compared to a clean 50s suburban neighborhood seen in Black Ops 1."
