MP9 | Bioleak
Sourced from the Chroma 3 Case and belonging to The Chroma 3 Collection, the MP9 | Bioleak is a Mil-Spec skin where varying shades of green are layered to create the illusion of a chemical spill spreading across the weapon. The biological hazard concept is communicated entirely through color gradation rather than explicit imagery. StatTrak editions are available. The float range runs from 0 to 0.5, capping at well-worn Field-Tested condition, where the green gradients begin to fade and blend together, softening the chemical-spill effect that defines the design.
