USP-S | Cortex by Glasgow died appeared in the CS:GO shooter on February 15, 2018. It is contained in the Clutch Case as one of seventeen weapon finishes. The case was added to the shooter in the “Welcome to the Clutch” update.

The handgun is covered with an image featuring a gray-green skull (on the grip), from which thick pink brain parts go all over the weapon's surface. The background (except for the gray-colored slide) is dark gray-brown and decorated with lighter crosses of various sizes. The brain cortex makes up the “USP-S” word on the silencer. The gun’s hammer is colored pink, and below it, there is a cross with a pink outline.

Float Value of USP-S | Cortex can vary between 0.06 and 0.80, so it is obtainable in any exterior quality category. As the weapon’s quality deteriorates, the handgun gradually darkens, and the paint gets erased from the slide. At maximum float values, almost the entire background layer is erased, but the image of the skull and brain parts remains relatively intact.

USP-S | Cortex belongs to the “Classified” rarity grade and is available with the StatTrak kill counter. The skin is popular among CS:GO players.
