IGN has updated their review for Call of Duty: Black Ops 2 with a run-down of Wii U-specific features and other things you should know about this version of the game. Luckily, the GamePad integration is praised, with a specific nod to the use of the touchscreen:
You can change your class without having to bring up the start screen, for instance, or call in Scorestreaks with on-screen buttons (less than ideal in an intense situation, but it is optional), or use the GamePad as your minimap regardless of what controller you’re using.
But in terms of the multiplayer:
…hardly anyone is playing right now. I could easily find games of Team Deathmatch, but finding games in other modes or in League Play is currently nigh impossible.
Feel free to share your experiences in the comments if you’ve picked up a copy of the game. You can also check out a video version of IGN’s review after the break.
