MP9 | Bioleak

Origin Story

The MP9 | Bioleak, released on April 28, 2016, as part of The Chroma 3 Collection, features a design that evokes a chemical spill with varying shades of green. Its in-game description, "Varying shades of green create the illusion of a chemical spill," sets the tone for its distinct appearance. The accompanying flavor text, "BEWARE DIRECT EXPOSURE," further enhances the theme of hazardous materials.

Drop Chance

MP9 | Bioleak is Mil-Spec, a Blue-tier skin, less common than base collection drops. From the Chroma 3 Case: approximately 11.42% per opening (roughly 1 in 9). The 79.92% Mil-Spec tier rate is split across 7 Mil-Spec skins in the case. StatTrak versions drop at ~1.14% from the Chroma 3 Case (about 1 in 88). These per-skin odds assume equal weighting within tier — Valve publishes tier rates but doesn't formally confirm even distribution across skins in a tier.

Skin Condition

Float range 0 to 0.5. Exteriors: Factory New, Minimal Wear, Field-Tested, Well-Worn, Battle-Scarred. StatTrak is available in FN, MW, FT, WW, BS.

• Factory New ($1.15): The anodized finish shows no signs of wear, maintaining its pristine appearance.
• Minimal Wear ($0.48): Minor abrasions may appear on the edges, but the overall design remains largely intact.
• Field-Tested ($0.43): Noticeable wear begins to appear on the weapon's surfaces, with some dulling of the anodized finish.
• Well-Worn ($0.40): The finish shows significant wear and scuffing, with larger areas of dullness.
• Battle-Scarred ($0.39): Extensive wear and scratching are present across the entire weapon, heavily obscuring the original finish.

Model

Bioleak uses the legacy MP9 model, introduced with Trichromacy on April 28, 2016. The inspect animation and third-person appearance match the original CS:GO version.
