Hello everyone, I have been hearing complaints from the players that they were unable to switch from the primary to secondary firing mode and vice versa. So, I have successfully fixed the issues with the very first update of Mission XAM game a week after its release. I am really sorry for the inconvenience caused due to the bug and there should be no interruption during the gameplay. However, I will keep providing more updates in the future as I continue to receive the Steam community feedback. Thank you very much for taking your time to play this game and I really hope that you will enjoy it! Features Added/ Bugs fixed: 1. Firing mode switching bug has been fixed. Press "1" to switch to the primary firing mode and "2" to switch to the secondary firing mode. 2. Added a sound effect when the weapon is switched. It was missing in the previous release build. 3. A few minor bugs are fixed. If you encounter any bug please feel free to let me know in the comments below or start a new discussion thread. Thanks to your patience! Best Regards, Anamik
