The show's upcoming promo calls Survivor: Kaoh Rong "the most punishing season yet"

http://canstatic.cbs.com/chrome/smart_tag/canplayer.jsWell, this looks awful.

CBS will begin airing its first Survivor preview since the newest cast was announced this weekend. In the First Look promo – obtained exclusively by PEOPLE – instead of playing the normal tribal music, the network is highlighting the suffering that the contestants endured.

Even in its “easier” seasons, the conditions of Survivor are brutal. Over the years, hundreds of contestants – including combat veterans and professional athletes – have told PEOPLE that playing the game was the hardest thing they have ever done.

If possible, this season is shaping up to be even harder.

By all accounts, the conditions of Survivor: Kaoh Rong were terrible. The show was filmed last spring off the coast of one of Cambodia’s largest islands. It was the rainy season, and the contestants were miserable. The show’s medics had to get involved several times.

The result? A game that producers call the franchise’s “most punishing season ever.”

In the past, some contestants have been pulled from the game due to severe injuries. Others have been evacuated because a small cut gets infected. With constant downpours, it’s hard to keep things clean. Combine the conditions with dangerous physical challenges, and it’s shocking that we don’t lose half the contestants every season.

(Oh, and FYI: the song in the promo is called “Get Up,” by the Los Angeles-based band Dorothy.)
