Counter Strike Online Wiki

The A Decoder was a decoder item in Counter-Strike Online.


This item was replaced by Mileage Decoder in later updates.

The A Decoder works similarly to the regular Advanced Code Decoder and Code B Decoder, as all three are compatible with the Code Box and sold in cash points. However, the real difference is that the A Decoder offers a different set of contents as opposed to the other two. Most weapons added are the Coded Box weapons from 2011 ~ 2012 and Volcano, the main prize of Letter Collecting Event in 2011.
