USP-S | PC-GRN was added to the game on March 31, 2025, as part of The Fever Collection, released with the Spring Forward update. The skin was created by Ksamand, Sheva, and jurgengusta. According to available information, this is the first weapon skin by all three creators to be accepted into the game.
The frame and grip are finished in green and turquoise shades and complemented by diagonal stripes. Most of the slide and the silencer have a dark silver metallic finish. The rear part of the slide features a translucent green plastic panel through which the weapon's internal components are visible. A similar translucent insert is present on the lower part of the grip. A small sticker with a pearlescent effect is located on the slide. Various parts of the body are complemented by white technical markings and inscriptions.
The skin's Float Value ranges from 0.00 to 0.90, which makes USP-S | PC-GRN available in all exterior conditions. The first minor abrasions appear on various parts of the body already in Factory New condition. As the Float Value grows, abrasions increase slightly in number and size. The weapon's surface gradually develops a patina, making the skin's color scheme warmer. At Float Values above 0.60, the skin begins to darken noticeably. At the highest wear levels, the green and turquoise areas take on a warmer tone, while the metallic surfaces become rich bronze. The paint layer is barely worn away, while all design elements remain clearly visible.
The pattern index does not affect the skin's appearance.
The quality of USP-S | PC-GRN is Mil-Spec Grade. The skin is available in a StatTrak version. According to the creators' concept, the design depicts an experimental weapon from a classified laboratory. The weapon is equipped with Glass of Fate technology, which allows its internal components to be seen through transparent parts of the body.
