I don't see why you couldn't. You can on PS3, and X-Box 360. I got Black Ops for Wii 2 days ago, I have not tried split screen but I believe it will work!
You cannot play split screen on the PC version
Yes you can!
yes
Call of Duty Black Ops is four player split-screen, and 2 can play split-screen online.
Just connect both controllers and go to multiplayer and split screen.
yes you can
No split screen for the wii, I know sucks.
go into multi player go into split screen.
WEEB
You can play online in Call of Duty Black Ops PS3 using the online split-screen support.
Sadly in black ops for the Wii you cannot play 2 player split screen like on the Xbox and Ps3 versions
if you go into zombies and do split screen you can.
