Got a job for you, Marked One...
The fire barrel provides warmth and light. It's found in all camps within the game. Some stalkers play a guitar, drink energy drinks or just talk around the fire. If you want to talk with them, stare at them for a long time till they stand up or jump over them.
- Due to a glitch, when you load a map (Military Warehouses, for example), some stalkers will spawn in the camp fire, get stuck, and die. The surrounding stalkers then act as if an enemy struck.
