CS2 Weapon Cases — Complete History

Valve introduced the first weapon case — the CS:GO Weapon Case — on August 14, 2013, alongside the Arms Deal update. That same update launched the entire skin economy and also added the M4A1-S, USP-S, weapon inspect (F key), and the eSports Case whose key sales funded competitive tournament prize pools. Since then, over 40 weapon cases have been released across CS:GO and CS2, each requiring a $2.49 key to open in-game.

Cases come in three categories: Black cases (Valve-designed skins with a standard CS:GO Case Key), eSports cases (Valve skins where key proceeds supported the competitive scene), and Yellow "community" cases (community-designed skins with unique keys, with proceeds shared with Workshop artists). Each case contains 17 weapon skins across five rarity tiers plus a pool of rare special items (knives and gloves).

Notable landmark cases include the original CS:GO Weapon Case, the Chroma Case (first knife finishes), the Spectrum Case (new knife types), the Dreams & Nightmares Case (community contest winner with over 15,000 submissions), and the Kilowatt Case. Discontinued cases that no longer drop in-game — like the Bravo Case and CS:GO Weapon Case — tend to climb in market value over time, making them collector items.

Trivia & Fun Facts

  • On September 11, 2017, Perfect World (Valve's Chinese partner) disclosed the exact case probabilities publicly — the first official confirmation of drop rates, revealing the 0.26% knife chance that players had long speculated about.
  • On October 28, 2019, Valve made all newly purchased keys non-tradeable and non-marketable to combat money laundering and fraud — a change known as the "Key Change" that shifted the entire CS:GO economy. Legacy keys bought before that date remain tradeable and now sell for $15–$100+ as collector items.
  • Case opening is completely banned in the Netherlands and Belgium due to loot box gambling laws. In France, cases cannot be purchased from the Steam Community Market but can still be sold.
  • An unused 3D model called "weapon_crate_a" was found in the game files long before cases received an opening animation in the Panorama UI update.
  • Each grade up in rarity has a 1:5 relative probability — meaning you're 5× more likely to get a Mil-Spec than a Restricted, and so on up the chain.

Most Popular CS2 Cases to Open

Some CS2 cases are more popular than others due to their rare and valuable skins. The Dreams & Nightmares Case is one of the most opened cases thanks to its striking community-designed skins. The Kilowatt Case and Gallery Case are among the newest releases with fresh skin designs.

Classic favorites like the Clutch Case, Chroma Case, and Fever Case remain hugely popular for their iconic knife finishes and coveted Covert skins. Every case has the same 0.26% chance of dropping a rare special item, but the specific knives or gloves you can get are case-specific — for example, the Kilowatt Case only drops Kukri Knives, while the Clutch Case only drops Gloves. Try them all free in our simulator to find your favorites.

Tips & Information

  • Knives and gloves have approximately 0.26% drop rate from cases — roughly 1 in 385 openings.
  • At $2.49 per key, that averages around $959 in keys per knife. StatTrak knives are even rarer at roughly 1 in 3,850.
  • Each case has different weapon skins, but all cases share identical rarity tier probabilities (disclosed by Perfect World in 2017).
  • StatTrak versions have a 10% chance on any eligible item you unbox.
  • In CS2, cases are obtained through the Weekly Care Package — you receive one after your first XP rank-up each week. You're shown 4 items (typically 1 case, 1 skin, and 2 stickers) and choose 2 to keep.
  • Discontinued cases (Bravo, eSports, original Weapon Case) no longer appear in the Care Package pool and have become collector items.

Frequently Asked Questions

What are CS2 cases?

CS2 cases (also known as CSGO cases) are virtual weapon containers in Counter-Strike 2. Each case contains a set of weapon skins across rarity tiers — from common Mil-Spec (blue) to ultra-rare Covert (red), plus a chance at knives and gloves. Cases require a key ($2.49) to open in-game, but you can open them completely free in our simulator.

How do CS2 case odds work?

CS2 case odds follow Valve's officially disclosed drop rates: 79.92% Mil-Spec (blue), 15.98% Restricted (purple), 3.20% Classified (pink), 0.64% Covert (red), and 0.26% for knives and gloves. There is no pity timer — each case opening is completely independent. StatTrak variants have a 10% chance on eligible items.

What is the knife drop rate in CS2 cases?

Knives and gloves have a 0.26% drop rate, meaning approximately 1 in 385 case openings. At $2.49 per key, that averages around $959 worth of keys per knife. StatTrak knives are even rarer at roughly 0.026% (about 1 in 3,850 openings). Our free simulator lets you experience these odds without spending real money.

Can I open CSGO cases for free?

Yes! Our case opening simulator lets you open all CS2 and CSGO cases completely free with real drop rates. No registration, no downloads, and no real money needed. Your virtual inventory is saved locally in your browser. It's the perfect way to experience case opening without the financial risk.

What are the best CS2 cases to open?

The "best" case depends on what you're looking for. Knife/glove odds are the same 0.26% across all cases, but the rare special items are case-specific — each case has its own pool of knife models and finishes (or gloves). For the most expensive potential drops, cases like the CS:GO Weapon Case, Kilowatt Case, and Dreams & Nightmares Case contain highly sought-after skins. Try them all for free in our simulator to see which cases appeal to you.

How many CS2 weapon cases are there?

There are currently 42 weapon cases in CS2/CSGO, starting with the original CS:GO Weapon Case released in August 2013. Valve releases new cases periodically — usually 2 to 4 per year — each containing 17 community-designed skins plus a rotating pool of knives and gloves as rare special items.

Are CS2 case odds the same as CSGO?

Yes. CS2 uses the same case drop rates as CS:GO. Valve disclosed these probabilities in 2017 and they have remained consistent through the transition to Counter-Strike 2. Our simulator uses these exact official rates for all cases, whether they were originally released as CS:GO or CS2 cases.
