I believe I saw it about 6 years ago on Pick TV (could be a few years out). I also think it was an English/Canadian drama series about a Fictional Survival Game Show (all the contestants were played by actors). Started out as an innocent game show, but soon became clear people were being killed off. There were various ways in which contestants died, such as the Helicopter to leave being a lie that left you dead and buried. I also recall a mysterious box of some kind. It also remember some sort of Native Tribe involved, as well as some sort of Militia (people with guns at any rate). If you can help in any way, it’d be amazing: i’ve been trying to recall it for some time.
