Using high caliber weapons such the 50.cal sniper or the shotgun cause to dismember enemies legs. Different enemies can have different behaviour after shooting their leg off:
- Zombies: Slows them down but they will crawl towards you.
- D-class: Will make agonizing screams and die bleeding out.
- MTF Soldiers or Security guards: After losing a leg they will simply equip a pistol and try to shoot you. Making no screams for lore reasons.
