Searchtool is a server browser for Internet games. It features the ability to ping servers, download a new serverlist, search for player(s), manage your favourite servers, connect to server of choice, and more. The intention was to create a new server tool for Linux. As a 'side-effect' this software also runs on other platforms as well because it is written in Java. So far supported games: Half-Life, UnrealTournament, UnrealTournament2003.
