There's a tendency to claim lots of things are a sign of the end times. Then there are things so unfathomably horrendous that you can't help but feel we're tumbling off a cliff edge into mass carnage.

The upcoming Russian reality show Game2: Winter will strand 30 men and women in the remote Siberian wilderness to compete for a cash prize. Per their contracts, contestants must also sign off on potentially being raped, killed or murdered, all of which the show is proudly "permitting".

"Everything is allowed," reads the show's press materials. "Fighting, alcohol, murder, rape, smoking, anything."
