The Thermal Scope, also known as the biosensor scope, is found in Chapter 13 of the game—the scope functions by showing you the heatwave map through the Scope attached to a gun. Through the Scope, you can easily spot enemies from afar as they show in Yellowish color that is vibrant and easy to spot.

Although it is just an attachment to a gun after chapter 13, where you find it, it becomes a vital part of your game. Without the Scope, you might struggle a lot to defeat certain enemies, and with it, it becomes much more manageable.

You will encounter the Scope simply by following through the main questline. However, to ensure you do not miss it or make it easier for you, we will show you where exactly you can find the thermal Scope in Resident Evil 4 Remake. After obtaining the biosensor scope, you can also sell to the merchant for 3,000 Pesetas, but be careful, as repurchasing it would cost you double the amount; of 6,000 Pesetas.

After you open the incubation lab, you must go inside a room with 4 Regenerators inside incubation cells.

Uses

The thermal Scope is an attachment that provides you with certain benefits in combat. While some are just bonuses, others are necessary to kill certain enemies. On the Island, certain areas are dark, and it’s harder to spot enemies. So you can use it to mark out enemies in the dark and get some good headshots.

The primary use of this scope can be driven by the time you get it in the game. After your first encounters with the regenerators, you will realize how challenging these enemies can be. In your first encounters, it will take countless bullets or some explosives to kill them. However, After obtaining the attachment, you will realize how easy it can become to take them out.

Regenerators are enemies capable of regenerating very quickly and are very hard to take out. But with the help of thermal Scope, you can mark out the three Plagas living inside its body. These Plagas can be seen through the Scope as bright yellow organisms residing inside the Regenerators whom you kill quickly by shooting at these Plagas.

Weapon Compatibility

The thermal Scope can be generally attached to any weapon that can use its scopes. These weapons include any rifle in the game except the LE 5 Submachine gun.

The list of the weapons compatible is:-

The SR M1903 is an early-game gun, so it is better not to use the biosensor scope. The CQBR Assault rifle and LE 5 SMG provide a reasonable fire rate, so you do not need to precisely aim at the vital points with this gun. However, due to its damage, the best weapon to use the biosensor scope will be the Stingray rifle.

If you have fully upgraded the Stingray, you can easily remove the Regenerators with three well-placed shots by spotting the plaga silhouettes inside their body.

You can open your briefcase and click on the gun to use the biosensor scope. Click the parts button and select the biosensor scope to attach it to the weapon.

Ending Remarks

If you do not have the thermal Scope, the main problem is to kill the Regenerators, which can quickly heal from any damage you give them. So it is necessary to have it to save your ammo and promptly take them out. Unless you plan to take them out by bombarding them with grenades, you will need a lot of resources. So it is better to obtain it while in the incubation lab.
