Nickelodeon halloween scary show?

There was this one show that was on nickelodeon during halloween a
couple of years back and I wanna know the name.

I remember it was like a scary game show where they made these kids do
challenges that seemed like they were out of a horror movie. I think
they were in some kind of camp too while they were there. I also
remember that they did almost everything during the dark. Does anyone
know the name?
