For Linux Users, after installing the game and extracting the .zip folder; make sure Steam(normal linux steam not the one using WINE) is running in the background after that open the installed game folder and before opening the game application go to the properties of the game application and click on the permissions tab and make sure "allow this file to run as a program" is checked and then open the game application normally and you should see the server list with the available online servers in your region and should work pretty smooth. this worked with me figured id tell other people.
