The Gamma Case drops one of 67 skins — rarities from “Mil-Spec” to “Covert”, with official odds (0.64% for the rarest tier).

With a 0.26% chance the case drops a rare special item instead — 50 knife or glove variants in this case.

The priciest drops are M4A1-S | Mecha Industries, Glock-18 | Wasteland Rebel, M4A4 | Desolate Space. The case itself currently costs $2.90 and needs a key to open.
