This TV/Game Show i watched?

Ok, so i dont know much about the show and i am trying to find out the
title.
So, there are like 10 contestants, and 1 host. Its all like dark and
gloomy and scary. What happens, is that you try to find money hidden
in an arena, and make it out. If you dont get enough money you lose.

Herews what happens: The contestants all go into 1 room and the money
is hidden in places. You crack things open, get electricutred, etc.
Then, you have to work as a team to open up the door(by collecting so
much money). You have to find so much money, then the door opens and
if you run out of time and are still looking for money, or obsticles
are closing in on you, the door closes and you are trapped in there
and lose the game.

Then at the end, the winner goes into a vault and is like chained up.
he tries to open drawers in the vault to find the keys to unlock him.
Then, if the person doesnt feel like he can make it, he presses the
panic button, everything stops, and the host appears in the door
saying "You pressed the panic button". PLEASE HELP! I REALLY WANT TO
KNOW WHAT IT IS CALLED, BUT I HAVE NOOO CLUE! Any suggestions are
helpful! thanks :)
