Currently the game's official page has an extremely basic server list with no sorting abilities.
Some users have set about creating third party server browsers in order to introduce more functionality.
Note: A few of the server browsers are showing up as false positives on a few AV programs. This is due to the coding of the program. These are all tested for viruses, and they are all safe.
