Released in 2015 with the Gamma Case, the Gamma Doppler variant of the Bowie Knife is one of the rarest and most coveted skins, known for its unique color patterns.

It exhibits a complex, wave-like pattern with shades of green, black, and purple, giving a metallic and almost alien-like appearance, with a primary color palette of green and black.

This skin is highly prized for its rarity and striking appearance, making it a favorite among collectors and enthusiasts despite its high market value.
