Here are some tips on how to defeat Screaming Mantis:
1. Equip the stun knife
Screaming Mantis can possess Dolls, which are small robots that will attack you. To prevent this from happening, equip the stun knife and use it to stun the Dolls. This will make them less of a threat and allow you to focus your attention on Screaming Mantis.
2. Use the Solid Eye
The Solid Eye is a gadget that Snake can use to see enemies through walls. This is particularly useful when fighting Screaming Mantis, as she likes to hide behind obstacles and attack when you’re not expecting it. Use the Solid Eye to keep an eye on her movements and to plan your attacks.
3. Take cover
Screaming Mantis will often throw large objects at you, which can cause a lot of damage. To avoid this, take cover behind objects in the environment. You can also use the Solid Eye to locate her and anticipate her attacks.
4. Use the Mantis doll
The Mantis doll is a small robot that you can find during the fight. It can stun Screaming Mantis, which can give you an opening to attack her. To use the Mantis doll, throw it at Screaming Mantis and then attack while she’s stunned.
5. Use the Mk. II
The Mk. II is a gadget that allows you to control a small robot. Use the Mk. II to stun the Dolls that Screaming Mantis possesses. This will make the fight much easier, as you won’t have to worry about them attacking you.
6. Use non-lethal weapons
One of the challenges of fighting Screaming Mantis is that she can possess your weapons, making them useless. To get around this, use non-lethal weapons like the stun gun or the tranquilizer gun. These weapons can’t be possessed, so you’ll always have a way to attack her.
7. Listen to the dialogue
As with all Metal Gear Solid bosses, there are clues in the dialogue that can help you defeat Screaming Mantis. Listen carefully to what she says and try to use that information to your advantage. For example, she may reveal weakness or tell you how to avoid her attacks.
In conclusion, defeating Screaming Mantis may seem like an impossible task, but with a little planning and strategy, you can overcome her psychic powers and progress through Metal Gear Solid 4. Remember to use the stun knife, the Solid Eye, and the non-lethal weapons, and listen carefully to what she says. Good luck!
