About the Winter Offensive Weapon Case
Winter Offensive Weapon Case arrived on December 18, 2013 during the "Winter Offensive" update and sits right in the late-2013 foundation layer of the case market. That age alone gives it a type of respect newer cases can never really manufacture.
Today it is priced and opened like a collector case. You are paying for early-case prestige, the classic knife pool, and the feeling of opening something from the period when the entire system was still being invented in public.
Trivia
- •This case is the first case to feature community-made finishes.
- •M4A1-S Guardian has a Counter-Terrorists symbol on its magazine and another smaller one on its suppressor.
- •M4A1-S Guardian contains a number of text printed on its suppressor and its receiver, all of which are not found on the normal M4A1-S:
- •Suppressor:CT Tactical Armaments, LLC.West Walley,UT USADEFIANCESerial No. 140869-ASN-C-U194Cal. 5.56 MM
- •Receiver:M4 CARBINECAL. 5.56MMW 461214
- •Five-SeveN Kami's name is most likely named after the Japanese word for paper, ç´™ (ã‹ã¿, kami), due to its manga theme.
- •Five-SeveN Kami's texture shows a page of manga created by its creator, Thurnip Oposto. Some of the contents of the texture reference gameplay in Counter-Strike: Global Offensive, and some of the Japanese texts on the texture are translations of descriptions found in Global Offensive. The texture for the Galil AR Kami in the Huntsman Weapon Case uses a rearranged version of the same texture.
- •M4A4 Asiimov (and by extension, the Asiimov family of skins) is named after science fiction author Isaac Asimov.
Key Facts
- •Knives: 0.26% drop rate
- •StatTrak™ variants: 10% chance on eligible tiers
- •Top item: ★ Karambit | Case Hardened — value depends entirely on the pattern, with the famous “Blue Gem” Karambit selling for over $1 million in private trades
- •Expected ROI: 30.7% ($6.12 EV per $19.95 opening incl. key)
- •Every opening is independent — past results don't change future odds
FAQ
Why is Winter Offensive Weapon Case still a collector case?▼
Because it comes from late 2013, when the case market still felt new and every release helped define the skin economy. That early status does a lot of the pricing work on its own.
What items are in the Winter Offensive Weapon Case?▼
The Winter Offensive Weapon Case contains 78 skins across 5 rarity tiers: 65 ★ Rare Special, 2 Covert, 3 Classified, 4 Restricted, 4 Mil-Spec. The rare special tier includes 5 knives across 17 finishes.
How do I open the Winter Offensive Weapon 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 Winter Offensive Weapon Case drop rates realistic?▼
Yes. The simulator uses the drop probabilities Valve publishes for CS2 containers. For the Winter Offensive Weapon Case, that means knives at 0.26% per opening.
What are the knives drop rates in the Winter Offensive Weapon Case?▼
Knives land at 0.26% per opening — about 1 in 385. The Winter Offensive Weapon Case has 5 knives across 17 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 Winter Offensive Weapon Case?▼
The ★ Karambit | Case Hardened is the headline pull, but its real value depends on the blue-pattern percentage rather than the listed Steam Market price. The famous "Blue Gem" Karambit (pattern 387) has reportedly sold for over $1 million in private deals, while ordinary patterns trade for a fraction of that.
When was the Winter Offensive Weapon Case added to CS2?▼
The Winter Offensive Weapon Case was added to the game on December 18, 2013, alongside the "Winter Offensive" update. It is classified as Container Series #7. It replaced the ESports 2013 Winter Case as the newest case.
How much does the Winter Offensive Weapon Case cost?▼
The Winter Offensive Weapon Case costs around $17.46 on the Steam Market as of May. Add $2.49 for the key and each opening totals $19.95. You can try it risk-free in our simulator before buying.
What is the expected ROI of the Winter Offensive Weapon Case?▼
30.7% — meaning a $19.95 opening (case + key) returns about $6.12 on average. Most value is locked behind the rare special items — the average opening returns less than cost.
Does the Winter Offensive Weapon 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.
