The Biosensor Scope is a really important item in the game. It is necessary for finding the wrench tool in the game, as well as dealing with the Regeneradors. Without this attachment, you cannot tell where the Plaga Parasites are located inside their bodies.

  • On this side of the Incubation Lab, you will come across a Biosensor Scope.
  • This is a special attachment that you will need in order to see the parasites inside the Regeneradors.
  • Killing these Plaga parasites is the only way to efficiently deal with these enemies, and the Biosensor Scope will help you locate them inside their bodies.
  • The Biosensor Scope can be attached to a number of weapons. You can attach it to the Rifle, The Stingray, or the LE5.
  • Pick your weapon of choice and attach the Biosensor scope to it.
  • Right next to the Biosensor Scope, you will find a file that tells us some important information regarding the location of the Wrench Tool.

We need the Wrench Tool for overwriting the terminal in Resident Evil 4 Remake.

  • The document tells us that during a recent power outage, a test subject awoke from cryogenic stasis and broke out of its holding tank.

  • That tool is the Wrench Tool that we are looking for.

Equip the gun onto which you just attached that Biosensor Scope attachment. Look through all of the tubes in the Incubation Lab, and you will be able to find one body that has a Wrench Tool inside of it. The Biosensor Scope shows you the X-Ray view of anything you view with it, so you can easily spot the wrench tool.

  • Shoot the tube with the Regenerador inside of it, and be ready to fight it.
  • Aim for the parasites inside its body to make quick work of it.
  • The parasites will be highlighted in yellow if you look at them through the Biosensor Scope.
