Backrooms: Code Yellow Entities
Every Backrooms: Code Yellow entity in one place: the monster list, dangerous entities, behavior patterns, and evasion habits that keep the squad alive.
What are Entities?
Entities are the hostile creatures roaming the Backrooms. Each one follows its own detection and attack pattern, and learning those patterns is the difference between a clean extraction and a squad wipe. This section catalogs every entity with practical counterplay.
Why Study the Entities?
Recognize Threats Early
Every entity announces itself somehow: sound cues, movement style, or the rooms it favors. Early recognition buys you time to hide or reroute.
React the Right Way
Running works on some entities and kills you against others. Match your response to the threat: freeze, hide, sprint, or break line of sight.
Protect the Squad
In co-op, one panicked mistake can cascade. Shared entity knowledge keeps the whole team calm and moving when a monster cuts through the hallway.
