Uses

The true value of this attachment became apparent when I obtained it in the game. After my initial encounters with the regenerators, I realized just how formidable these enemies could be. In those early encounters, it took an excessive amount of bullets or explosives to even stand a chance against them. However, once I had the thermal Scope, the tables turned dramatically.

Regenerators were notorious for their rapid regeneration abilities and their resilience. Yet, with the thermal Scope, I could identify the three Plagas residing inside their bodies. These Plagas appeared as bright yellow organisms when viewed through the Scope. By targeting and shooting these Plagas, I found that dispatching the Regenerators became a much quicker and easier task.

Would I Recommend?

The thermal Scope was a game-changer for me in combat, offering several advantages. While some were nice bonuses, others were essential for dealing with specific enemies.

On the Island, there were dark areas where spotting enemies was a real challenge. That’s when the thermal Scope came to my rescue, allowing me to mark out foes in the darkness and score some precise headshots.

If you do not have the thermal scope, the main problem is killing the Regenerators, which can quickly heal from any damage players deal. So, it is necessary to have it to save your ammo and promptly take them out.
