The MP9 | Goo (Field-Tested) is the kind of skin that looks like someone spilled a vat of radioactive Nickelodeon slime on a submachine gun and called it art. The neon green "goo" oozes over the weapon in a way that’s equal parts mesmerizing and slightly nauseating, like a science experiment gone wrong. In Field-Tested condition, the slime starts to peel and fade, giving it that "I’ve seen better days" vibe—perfect for players who want to flex a skin that’s both cheap and meme-worthy. It’s not exactly intimidating, but hey, at least you’ll die in style… or maybe just look like a walking glow stick.
