When I fought Screaming Mantis on MGS4 I thought it was tremendously hard and confusing, so I thought I should write an articulo on fanpop on how to beat her.
Screaming Mantis posseses the uncanny ability to control peoples nanomachines which means even Meryl is trying to kill you, Akiba is not effected because he has no nanomachines. The dead bodies of beaten FROGS soilders come up and start shooting at you. Drebin put nanomachines inside tu so unfortunately she can control you, but there is a way to stop it, when Mantis is controlling tu use the syringe that Naomi gave tu and it will supress...
