Forget everything you know about a You Don't Know Jack game because YDKJ’s horribly deformed, mutant offspring Headrush has been birthed! Twisted animation, insane question types, and a bizarre appetite for all human excretory fluids and gassed add up to the most over-the-top YDKJ game ever! Fire this game up and stand back, because this is not your Mommy and Daddy’s 'You Don't Know Jack'!
