Unboxing in Counter-Strike Online, or more popularly known as decoding is a microtransactional feature, giving players the chance to win mainly exclusive weapons and classes not purchasable in the Shop. 

Since its debut in 2009, the decoders have gone through major revisions by including new contents over time. To date, there are 6 types of decoders, with each one varying in price, contents and the probability.

By using a decoder, a player is provided some mileage points which can be accumulated, and spent on the Mileage Auction feature. Mileage points do not expire unless they are used up.


Decoders can be bought from the Store, earned through events, received from leveling up as well as receiving them through the in-game gifting system.

The interface is brought up by clicking on the DECODER button at the bottom-right corner of the screen.

Decoder Interface

By clicking on each decoder type, the list of exclusive items are displayed on a grid. Players can learn more by mousing over an item, and right-clicking on it to view its description. If that is not enough, there’s also the PREVIEW button to see how it works.

Using a decoder gives a random item, along with a small amount of Mileage Points. If one is lucky, he or she will win any permanent exclusive on the grid which is shown. Generally decoders with popular and powerful items tend to cost more.

The only exception is the UNLIMITED decoder which guarantees a permanent item, but is also the most expensive type.

Decoder Results


As the name implies, the mileage auction is a marketplace for players to search, purchase items from other players and auction theirs at their own prices. While this feature is seasonal, the auction is accessible 24/7 until the next update schedule comes along.

Since it’s a free market, players are free to set prices as they wish. It is totally normal to see popular weapons being listed at sky high prices, because of their in-game performance, as well as their rarity. Items that are no longer available to purchase or have been discontinued might also fetch similar prices.

Success Bid

The general auction rules apply:

  • The first bid placed on an item includes 30% commission
  • Only one item allowed per bid.
  • Buyout immediately ends the auction and the item is rewarded to the buyer.
  • An auctioneer/ seller can sell up to 5 items at a time.
  • Once an item is successfully auctioned off or purchased by another player, the auctioneer/ seller receives the net price.
