Screaming Mantis is the final Beauty and the Beast Corps member, encountered in Act 4. She controls the minds of soldiers and even Snake. The key to defeating her is to use the Syringe (obtained earlier in the act) to break her mind control. Once she's vulnerable, shoot the two 'Psycho Mantis' dolls she carries to stun her. Then, inflict damage with any weapon. For a non-lethal approach, use tranquilizer rounds on her after stunning her. In her Beast form, she becomes more aggressive and manipulates the environment. Continue to use the Syringe and target her dolls. Her doll is obtained via non-lethal means.
