MP9 | Goo is a Restricted SMG skin from The Spectrum 2 Collection, which entered the CS2 economy alongside the Spectrum 2 Case in September 2017.

The float range for this finish is restricted to 0.00–0.60, so Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred are the only obtainable conditions on the open market. The restricted range is set by Valve at the time of release.

Both StatTrak™ and Souvenir variants exist — the StatTrak™ counter tracks confirmed kills, while Souvenir copies drop only from cases collected during Major Championship matches. Active listings for MP9 | Goo are tracked across 22 marketplaces, with prices spanning $0.84 to $500.00 depending on wear, variant, and seller.
