Vamp is a recurring antagonist. Your primary encounter with him is in Act 4. He is incredibly fast and uses knives. The key to defeating him is to use the Syringe (obtained from Naomi) to disable his nanomachines, making him vulnerable. Once injected, he can be damaged by any weapon. For a non-lethal approach, use tranquilizer rounds after injecting him. He will revive multiple times, requiring repeated injections. Focus on quick CQC counters and precise shots when he's vulnerable. This fight is more about timing and resource management than raw firepower.
