GameSpot writes: "When compared to the next-generation consoles, the cacophony of war may not sound quite the same on the Nintendo DS, but developer n-Space has worked on several portable Call of Duty games to get an idea of how to translate a first-person military shooter to the handheld. Call of Duty: Black Ops includes several new features in response to fan feedback; most notably is the addition of button controls, so that instead of relying on stylus controls, you are free to switch back and forth between the two--or whichever is most comfortable and will yield the fewest number of hand cramps."
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."
