Despite its usually lighthearted tone, the game is still set during the Zombie Apocalypse and has it's fair share of nightmarish scenes.
- A late season one radio mission features a guest reflecting on how his more technically-minded friends set up a series of automated traps in their base to ward off zombies. The last one on the list was an electric plate that would fry anything that stood on it. He then goes on to describe in great detail the sight and smell of seeing their corpses floating in the building, as the roof leaked the first time it rained and electrocuted them all in their sleep.
- A former designer for a video game talks about how Left 4 Dead provided his friends with enough knowledge of teamwork to survive the trip to Abel - aside from the friend who injected himself with adrenaline and suffered a heart attack. The thought that gameplay clichés could cause unnecessary deaths is a very real and frightening thought.
- Undead Children are a common occurrence within the game world. Janine may warn the player of a whole swarm of them during a Tech Supply Run.
