About the Gamma Case
Released on June 15, 2016 as part of the "Gamma Exposure" update, Gamma Case is remembered for the finish family as much as the case itself. Once Gamma-era finishes arrived, the case basically wrote its own long-term relevance.
Players still chase it because the rare-special pool is easy to understand and still feels premium. With Gut Knife, M9 Bayonet, Flip Knife, Bayonet and Karambit in finishes like Gamma Doppler, Autotronic, Freehand, Black Laminate, Bright Water and Lore, Gamma lives in the same space as Chroma: you are buying into a finish idea first and a specific case second.

- •1337 Krew (leetspeak version of Elite Crew)
- •BURN IT DOWN (overlaid on a painted Molotov Cocktail)

FAQ
What made Gamma Case so memorable?▼
It is the case most players associate with the arrival of the Gamma-era finish family. Once Lore, Gamma Doppler, and the rest of that look entered the game, the case immediately got a long shelf life.
What items are in the Gamma Case?▼
The Gamma Case contains 67 skins across 5 rarity tiers: 50 ★ Rare Special, 2 Covert, 3 Classified, 5 Restricted, 7 Mil-Spec. The rare special tier includes 5 knives across 6 finishes.
How do I open the Gamma Case for free?▼
Use the simulator on this page. It runs Valve's published drop probabilities, so the unboxing pattern matches the real case. You can also see the expected ROI before committing real money to it. No login or download.
Are the Gamma Case drop rates realistic?▼
Yes. The simulator uses the drop probabilities Valve publishes for CS2 containers. For the Gamma Case, that means knives at 0.26% per opening.
What are the knives drop rates in the Gamma Case?▼
Knives land at 0.26% per opening — about 1 in 385. The Gamma Case has 5 knives across 6 finishes, so the odds of pulling one specific finish are noticeably lower than the headline number suggests.
What is the most valuable skin in the Gamma Case?▼
The ★ Karambit | Gamma Doppler (Emerald) is the top pull, valued at up to $8,846.52 on the Steam Market.
When was the Gamma Case added to CS2?▼
The Gamma Case was added to the game on June 15, 2016, alongside the "Gamma Exposure" update. It is classified as Container Series #144. It replaced the Chroma 3 Case as the newest case.
How much does the Gamma Case cost?▼
The Gamma Case costs around $4.90 on the Steam Market as of May. Add $2.49 for the key and each opening totals $7.39. You can try it risk-free in our simulator before buying.
What is the expected ROI of the Gamma Case?▼
56.8% — meaning a $7.39 opening (case + key) returns about $4.20 on average. Most value is locked behind the rare special items — the average opening returns less than cost.
Does the Gamma Case have StatTrak™ items?▼
Yes. Non-special skins can drop as StatTrak™ at a 10% chance. The variant tracks in-game kills and usually trades at a premium over the standard version.
