In Case Simulator 2 you can increase your chances of earning a valuable souvenir by downloading Case Simulator2 to your device. It allows you to access weapons chests indefinitely, change models, and read all details about the characteristics of each weapon in the detailed description. It also allows you to calculate your chances of getting a specific weapon sample.
You can also divide the entire arsenal into different ranks and mark them differently depending on what you need. The creators of this project have taken into consideration the fact that samples received may differ in quality.
