NBC had a half-hour preview of the show on Saturday and golly does it look like a mess. Quite literally in this preview, since it involved the contestants dragging themselves through a muddy field to find cases.
It is exactly what it sounds like it is, a blend of Survivor-style challenges and the classic DOND game. Because you don't actually have to "survive" on the island they've cast a wider net than Survivor would in selecting their contestants. This group includes a skinny kid and a 62-year-old woman. Still, the challenges are physically demanding, and it doesn't seem fair that those two are competing against far more athletic specimens of humanity.
The rules are...confusing, so far, and will probably take a full episode (or two) to make sense. Suffice it to say that the entire first half-hour featured no actual DOND game play. Instead, we're treated to the spectacle of the challenge, a lot of mumbo-jumbo about what the players need to do, and the inevitable cutaways of the players telling us what they're thinking and how they're going to win. It was a lot, without being very much at all.
