USP-S | Caiman by OniLolz and Zaphk appeared in CS:GO on June 11, 2014. The skin is contained in the Huntsman Weapon Case that was introduced to the shooter in the “Phoenix comes to a close” update. This item appeared in the case after USP-S | Orion (copyright issues) was removed from it.

The slide of the pistol features a profile view of a caiman's head – a reptile from the Alligatoridae family, native to Central and South America. The animal's very noticeable dark-orange eye matches the color of the pistol's grip.

Float Value of USP-S | Caiman can vary between 0.00 and 0.40, allowing the skin obtainable in any exterior quality category, except for the “Battle-Scarred” one. As the weapon wears down, the paint gets gradually erased from its surface, and the silencer gets covered in scratches. At the highest possible float values, the pistol appears significantly worn and scuffed, but the reptile's eye remains distinguishable.

USP-S | Caiman belongs to the “Classified” rarity grade and is available with the StatTrak kill counter. The skin is not popular among CS2 fans.
