The "Server under maintenance" message means that we are updating the game servers to provide you with the best possible gaming experience.
 
It usually takes no more than a few hours. After that, you will be able to continue playing as usual. Do not worry, no one will be able to fight you during the maintenance.

Please do not reinstall C.A.T.S. when you see the maintenance warning, as this may result in the loss of your game progress.
