Radioactive Area

Permanently Closed - A poisonous gas is filling the underground complex. You've all escaped into a bunker room in order to stay safe and escape the toxic gas from killing you. At first it seems like the perfect place to be, until you realise that in the event of an emergency the entire base is rigged to self destruct . . . including the room you are in. Your only chance for survival is to shut off the self destruct sequence, but the button to stop it is locked. You have 1 hour to get the lock open and shut off the self destruct sequence before you're all blow up - along with the rest of the complex.
