At a glance

knife | Gamma Doppler (finish 570, Gamma Doppler Phase 2) is one of the louder finishes in CS2 knife skins: multicolor anodized work with a mythical tag, built for all tactical knife models. Valve’s pitch is deliberate — layered black and silver metal reads like marble veining, softening how “sharp” the blade feels in inspect and pushing the skin toward display and collection rather than pure flash.

Release & where it drops

Shipped 2016-06-15 in the Gamma Exposure update (official catalog entry, not a Workshop-signed skin). It sits in the Gamma Case pool with the rest of that gamma-themed wave — knives, gloves, the lot. On C5GAME or Steam Community Market, narrow case line + knife model first, then fight over pattern and float inside the same Phase.

Specs that matter when you shop

| Field | Detail |
|--------|--------|
| Category | Knife (shared finish) |
| Finish | Gamma Doppler Phase 2 |
| Rarity | Mythical |
| Craft | Multicolor anodized |
| Wear | 0.00 – 0.08 |

That 0.08 cap is tight. Most listings live in “near Factory New” territory; a small float bump often shows up faster than on skins with wide wear ranges. Spin inspect: metal highlights and color band edges shift with angle — that’s the whole point of the finish.

What to inspect (don’t trust the thumbnail)

Pattern placement: Doppler money is usually in the 3D inspect — how much of the blade the bands cover and where they sit. Same Phase, different knife; always compare item to item.

Wear tiers: Top of the range (~0.00) is the best you’ll see inside the allowed window; even toward 0.08 you’re still in light wear, but tip, edge, and guard scuff first — zoom those in screenshots or in-game.

Liquidity: Mythical knife finishes don’t flood the market; price swings hard on model × pattern × float. Before you commit, pull the exact knife quote on C5GAME and cross-check Steam listings so you’re not paying Phase 2 prices for another doppler variant or Phase.

Shop verdict

Buy if you want a cool-toned, marble-metal doppler that’s less neon than some phases, you’ll full-spin inspect before paying, and you’ve matched Phase 2 + float + pattern to the knife you actually want.

Pass or pause if you’re shopping from icons only, you need ultra-forgiving wear (this finish doesn’t give you much room above mint), or you haven’t verified the seller’s phase and model against catalog 570.

Editor’s notes

Gamma Doppler Phase 2 is the “interior design” doppler — black-silver layers doing marble duty instead of screaming saturation. The 2016 Gamma Exposure drop date matters less day-to-day than the Gamma Case link: that’s your mental anchor when someone lists “gamma doppler” without saying which phase. I treat 0.08 max as a feature and a trap — feature because the knife stays visually clean longer in theory; trap because buyers still treat tiny float gaps like lottery tickets. Last habit: one full inspect rotation, then check C5GAME and Steam on the same knife, same float band — doppler shopping is comparison shopping, not impulse.
