MP9 | Mount Fuji

MP9 | Mount Fuji released September 21, 2021 as part of the Operation Riptide Case.

It originally released during the CS:GO era, before Valve's Counter-Strike 2 relaunch in September 2023 — its artwork, wear range, and source carried over unchanged into CS2.

It launched as a Restricted-tier finish, with both a StatTrak™ and a Souvenir edition.

As a finish, "Mount Fuji" is applied to the MP9 — the Counter-Terrorists' fast-firing, low-cost submachine gun — and carries the purple rarity color every Restricted-tier skin shares on the Steam Market and in-game.

That Restricted classification places it in the middle of the rarity ladder — rarer than Mil-Spec Grade, but short of the Classified and Covert tiers above it.

MP9 | Mount Fuji ships in all five wear conditions, but its float is capped between 0.00 and 0.55 — narrower than the full 0.00–1.00 range some other skins allow.

As with every CS2 skin, lower float values look cleaner: Factory New copies (roughly below 0.07 float) show the finish at its sharpest, while Field-Tested and Well-Worn pieces make up the most commonly traded middle ground between mint and heavily worn.

MP9 | Mount Fuji comes from the Operation Riptide Case — the Case is no longer part of the active drop pool, so trading and the Steam Community Market are the ways to acquire it today.

Valve's own published Case odds put a Restricted-tier pull like this one at roughly 1 in 31 (3.1960%).

There's both a StatTrak™ and a Souvenir edition of this finish, alongside the Normal version — three ways to own the same look, differing only in that badge.

Beyond that, there's no separate "phase" or pattern family tied to this finish in the site's data — it's tracked as a single fixed look across every wear condition it ships in.

As a Restricted-tier finish, MP9 | Mount Fuji sits among the more common pulls from the Operation Riptide Case rather than being a chase item — a straightforward, affordable way to add a MP9 skin to a loadout or collection.

Its StatTrak™ and Souvenir editions tend to trade at a premium over the Normal version, the same pattern seen across most CS2 skins with that variant available.

MP9 | Mount Fuji has been part of the Operation Riptide Case since September 21, 2021, and like every CS:GO-era CS2 skin, carried over unchanged when Valve relaunched the game on the Source 2 engine in 2023 — the artwork, wear range, and source Case/Collection are the same today as they were before the migration.

It's one of 5 Restricted-tier items in the Operation Riptide Case, out of 17 items total.

This is one of 47 MP9 skins currently listed on the site, spanning multiple rarity tiers.
