About the Gamma 2 Case

The Gamma 2 Case landed on Augu 18th, 2016 with the “Double Exposure” update, marking Container Series #172. Inside, you'll find 67 skins spread across 5 rarity tiers. The chase items are the 5 knives across 6 finishes sitting at the top with a 0.26% drop chance. The most valuable drop is the ★ Karambit | Gamma Doppler (Emerald), worth up to $9,056.38 on the Steam Market.

Currently sitting at 90% popularity (extremely popular), the Gamma 2 Case ranks among the most sought-after containers in CS2. The community rates it 4.7/5 across 9.5K votes. Notable pro players who own it include kennys, s1mple, happy.

On the Steam Market, the Gamma 2 Case trades at around $5.35. Factor in the $2.49 key and each opening runs you $7.84. Not sure it's worth the key? Open it here first — same odds, zero cost.

Based on current Steam Market prices and real drop rates, the Gamma 2 Case sits at 54.1% ROI — for every $7.84 you spend (case + key), the average return is about $4.24 in items. Like most weapon cases, the math favors Valve — but a knives pull flips the equation entirely. That's the gamble.

Trivia
