The key to defeating Mantis is to shoot down her Sorrow and Mantis dolls, both of which she will eventually drop. Eventually she will try to use Meryl and Johnny to shield herself. Shoot them out of the way (with tranquilizer rounds) and keep fighting.
To defeat Psycho Mantis, the player must switch their controller to the second player port. This prevents Psycho Mantis from reading Snake’s mind. The same tactic is used for the PS2 version of Metal Gear Solid, but people playing it on PS3 will have to change the controller ports via the menu.
At the end of the cutscene, Psycho Mantis forces Meryl to shoot Snake, and Snake must stop her without killing her. You can either knock her unconscious and deal her light damage, or just throw a STUN grenade to knock her out. In either case, the action will be followed by another cutscene where Psycho Mantis reveals himself.
At the beginning of the fight, simply walk away from Vamp when he comes towards you and hit him in the head with shots. When he approaches you, he’ll stop and pose before lunging at Snake with a quick melee attack. When he does, put down your weapon and run (or dive) perpendicular to Vamp’s movement path.
Behind the scenes. Screaming Mantis appears as a boss in Metal Gear Solid 4: Guns of the Patriots. Her form of beauty is based on the actress Scarlett Chorvat.
Oh forgot to say you can defeat Mantis without switching controller trick by destroying the flying busts/statues with a weapon like the Socom. I’ve found that this trick with the busts only works if you’ve already died once during combat and selected “Continue” and then try it.
Meryl will succumb to Psycho Mantis mind control and point her pistol at you. She will try to shoot you so you have to stop her. The best way is to KO them with a stun grenade, otherwise a combination of single hits will eventually stun them.
