They can regrow their limbs, making fighting them impossible if you do not know how to. The Regenerators will continue to haunt you throughout your journey if they are not killed. Here are strategies and tactics to effectively fight against these enemies.

Where To Find The Biosensor Scope

The Regenerator will first make itsappearance inChapter 13. As their weak spot is not visible to you at the moment, running away is the best course of action. However, that does not mean you will always need to run away from them.

As youexplore theLaband avoid the enemies, you will have to make your way to theDissection Room, where you will have to solve a puzzle tograb theLevel 1 Key Card. Once you acquire the Key Card,switch the power to theFreezerand go there. This is where you will find theLevel 2 Key Card.

After acquiring it, go to theIncubation Laband head to the control room. Here you will find a case inside of which is theBiosensor Scope.

Once you have acquired theBiosensor Scope, you mustattach it to a compatible weapon.

It can be attached to a few weapons, andthe sensor will allow you to look at the enemy through thermal vision to locate the parasite inside their body.

You can acquire the Stingray for 30,000Pesetasfrom the merchant.

CQBR AR

It is inside a locked box that you find inChapter 10. Alternatively can be bought from the merchant.

LE5

It is located inside the Freezer Room inChapter 13.

Attaching the sensor to a sniper such asStingrayis an excellent choice. If you do not have the money to spend on the weapon, you can still useCQBR ARorLE5,which are also great options for mid-range.

Killing Regenerators Quickly

A deadly attack that the Regenerators tend to do is tostart crawling on the ground.They are much faster when on the groundand close the distance relatively quicker,allowing them to pounce on you.Try to stay away from them when this happens.

AsBiosensor Scope can only be used on ranged guns, this will allow you to fight off these monsters from afar.

The Regenerator canextend its arms and attack you from a distance.This deadly attack can deal high damage, butit can be parried with a Knife if you’re able to get the timing down.

Try to be aware of your surroundingsthroughout the fight. This is because you findmost Regenerators inside small roomswhere you can be backed into a corner, leading to your death.

If you aim to kill the enemy quickly, you will need to use a couple of items to make the fight much easier and shorter. As soon as the enemy is aggressive towards you,throw a Flash Grenade at the Regenerator, which will temporarily stun it.

This will give you enough time to aim at the parasites inside its body and destroy them while it cannot react.

You can also throw a grenade near the area of the body where the parasite is located to deal high damage to it.Having multiple Flash Grenades will allow you to stun-lock the boss and take out the parasites in less than a minute.

Shotgunsare also a great option, as they can obliterate the enemy’s health bar.Once the parasite is exposed, a few shots from a Shotgun destroy it. Recommended options areW-870andStrikerShotgun, which have high damage output.

Using a Knife at close range is not ideal, as Knife in the remake is much weaker and decreases in durability.

If you are persistent,you may use the Knife to attack the enemy revealing its parasites and parry any attacks it does. This is difficult, but an alternative method if you do not have the Biosensor Scope.

In the latter chapters, you will encounter more Regenerators that look the same at the start, but after you destroy the parasites within them, they will mutate and turn intoIron Maidens, which spikes all over their bodies. These monsters have their weak spot located near their mouth and are quite tanky.
