Glock-18 | Mirror Mosaic was added to the game on September 16, 2025, as part of The Genesis Collection, released with the Show Off update. The skin was created by Sorarox. Another work by the artist, Sawed-Off | Spirit Board, was previously added to the game.
The pistol's slide is decorated with a geometric pattern of triangular elements forming a mirror mosaic. Similar sections of the pattern appear on the frame and grip. The mosaic has a glossy surface with a pearlescent effect. Its color scheme includes blue, turquoise, and purple shades that change depending on the lighting and the position of the weapon. The remaining parts of the body are painted solid gray. Several triangular icons and the inscription GLOCK AUTOMATIC appear on the body.
The skin's Float Value ranges from 0.00 to 1.00, which makes Glock-18 | Mirror Mosaic available in all exterior conditions. The first minor abrasions appear on the painted parts of the pistol in Field-Tested condition and become clearly noticeable at approximately 0.35. As the Float Value rises, abrasions increase in number and size. At the highest wear levels, the painted parts of the body are covered with large abrasions. The mirror mosaic becomes duller, and its pearlescent sheen becomes less pronounced.
The pattern index does not affect the skin's appearance.
The quality of Glock-18 | Mirror Mosaic is Classified. The skin is available in a StatTrak version. In the Steam Workshop, Sorarox presented the Mirror Maze series, which includes seven works. Glock-18 | Mirror Mosaic is one of them.
