Call of Duty: Black Ops 2 is practically a must-have for Wii U gamers who don't already own the game on another system. It marks really the first time a CoD game has been ported to a Nintendo system without requiring major compromises, thanks to the Wii U's increased power.
It plays identically to the PS3, Xbox 360 and PC versions, and thanks to the Wii U's GamePad it comes with some extra functionality as well. During multiplayer, the GamePad's screen can serve as an interactive map and can be used to select loadouts, score streak rewards and more.
And of course, you can pull the game down to the GamePad's screen and play it directly from the controller when someone else wants to use the TV (or when you have to take a shit, provided the bathroom isn't too far away from the console). Brilliant.
