Many guns are pointed at characters this episode

Constant use of harsh language including: fuck, shit, bitch, asshole, pussy, etc.

The more intense the situation, the more harsh language is said.

One of the characters was a drug addict before the sleep plague.

Characters use any drugs they can find (legal and illegal), to stay awake. This includes pills, cocaine, adrenaline, etc.

Because of the scenario, drug use is pretty much non-stop throughout this series.

While there is a good amount of humor throughout the show, a lot of times the show is hopeless, suspenseful, and disturbing. Even compare to the darkest moments of Rooster Teeth's other shows (Red vs. Blue, RWBY), this is darker by a huge margin. This is Rooster Teeth's darkest show to date.

Hallucinations and insane survivors can get be very disturbing.

A lot of character deaths are very tragic.

Bodies of dead children are sometimes seen.
