Souvenir MP9 | Bioleak (Factory New)

The MP9 | Bioleak is a CS2 weapon skin based on the CS:GO (legacy) model family, carrying over to the current Counter-Strike 2 ecosystem. Introduced through the Chroma era of releases, it became recognizable for its bold, contaminated “bio” theme and distinctive patterning. As part of the move from older CS systems to CS2, collectors continue to search for it due to its consistent look across Factory New to Battle-Scarred conditions.

Classified as a Mil-Spec Grade skin, Bioleak sits in the mid-tier rarity bracket. While exact drop chances are not publicly guaranteed in a specific, skin-by-skin way, Mil-Spec items are generally more attainable than higher rarity tiers. For players focused on long-term acquisition, its availability across standard container loot makes it a common target when opening the right case rather than waiting for rare market spawns.

The MP9 | Bioleak is available with multiple wear states: Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred. StatTrak™ is available for this skin, letting you track kills with the weapon. A Souvenir version is not available, and the skin’s float range is 0.000000 to 0.500000, covering everything from clean finishes to heavily worn appearances.

Visually, the Bioleak finish delivers an intense, bio-hazard-inspired aesthetic—featuring vivid green and dark accents that resemble leaked chemicals or organic contamination. The pattern style is tied to the provided paint index (549), which influences how the artwork and colors are laid out on the model. Depending on wear, the contrast and sharpness of the design can change noticeably, with lower wear levels typically presenting a cleaner, more readable pattern.

To obtain the MP9 | Bioleak, look for it within the Chroma 3 Collection and specifically via the Chroma 3 Case. This makes it most directly accessible through container openings associated with that collection line. For players building a themed loadout, it’s a natural fit alongside other Chroma 3 skins, especially those that share energetic color palettes and aggressive, graphic finishes.

In the community, Bioleak is often appreciated for its bold identity and how well it stands out on the MP9 platform. Because it’s a Mil-Spec skin with a recognizable design, it appeals to both practical players who want a clean, modern look without chasing high-rarity items—and collectors who focus on case-era skins and paint-index consistency.
