Killing Floor 3 was released on 24 Jul, 2025.
Killing Floor 3 contains the following elements that can be considered mature content: Graphic Violence: Players engage in first-person combat against bioengineered humanoids and monsters ("zeds") using firearms, sci-fi and flame-based weaponry, explosives, and melee weapons. Combat is extremely intense, with frequent depictions of dismemberment, decapitations, and exploding body parts. Realistic blood effects and slow-motion "Zed Time" sequences amplify the impact of gore. Blood and Gore: Environments and characters are frequently splattered with copious amounts of blood. Dead enemies often remain in the environment as mutilated corpses, and some weapons cause extreme bodily trauma such as melting, burning, or tearing of flesh. Strong Language: Dialogue and voice lines contain use of strong profanity spoken by both characters and NPCs during gameplay and narrative sequences. Disturbing Themes: The game’s narrative involves biological experimentation and body horror which may be unsettling to younger audiences.
