You Don't Know Jack Party comes to iDevices via Airplay for couch co-op
*Courtesy of a press release
I like the concept, but it seems to be kind of a happenstance feature. You need a device that utilizes AirPlay, plus you need to have 3 friends who also use Apple devices. Not as impossible as something like Zelda 4 Swords, but a few stars do need to align for this to happen.
So now you can You-Don't-Know-Jack-off on your couch! Sweet!
