Chroma 2 Case odds
Valve has disclosed the same rarity odds for every standard weapon case. The Chroma 2 Case follows them:
| Rarity | Chance per case | About 1 in |
|---|---|---|
| Mil-Spec | 79.92% | 1.25 |
| Restricted | 15.98% | 6 |
| Classified | 3.20% | 31 |
| Covert | 0.64% | 156 |
| Knife / gloves | 0.26% | 385 |
A knife is therefore roughly a 1-in-385 drop, and each case also needs a key. On average that makes unboxing one of the most expensive ways to get a knife. See CS2 case odds explained.
Chroma 2 Case and knife trade ups
Since the October 2025 update, five Covert skins can be traded up into a knife or pair of gloves. The result is drawn from the rare pool of the case your Covert inputs come from. So five Covert skins from the Chroma 2 Case can only give knives from the list above.
That makes the pool's average value the number that matters: a trade up aimed at the best knife in this case can just as easily land on the cheapest one. Mixing Covert skins from different cases splits your odds between their pools.
Price it before you sign. The knife trade up calculator lists every possible result from this case's pool with odds, predicted float and expected value at live prices.

Is the Chroma 2 Case worth opening?
Opening any case is a paid random draw: most openings return a Mil-Spec worth far less than the case plus key. If you want a specific knife from this pool, buying it outright is almost always cheaper. If you want any knife from the pool, compare the price of five Covert skins from this case against the pool's average value in the calculator.
