Plenty of games don't even include splitscreen multiplayer anymore, but Black Ops 2 on the Wii U has the most hardcore splitscreen we've ever seen. It's so hardcore that it doesn't even make you split the screen at all—with one player on the TV using the Wii U's Xbox 360-like Classic Controller, another can play directly from the Wii U GamePad's screen. That type of set-up will thwart screen-looking cheaters once and for all—as long as you make the person on the GamePad face the other way.
You can even have up to three players on the screen, with a fourth on the GamePad, or just four on the screen using the Classic Controller. It's extremely versatile.
