Click "Online Combat" from the main screen to see a list of games in progress (servers). From here, you may join a game, add a server to the list by IP address, or get detailed information on servers. When you play on a server, it is added to your "My Servers" list for your future convenience.
To host your own multiplayer game or play against bots, click "Host Game" from the main screen. As God of your own server, you have an array of options at your disposal. Once in-game, you will have the ability to kick or ban problematic players from the Scoreboard screen. You may also restart or change the game at any time.
When hosting your own game, you can earn money by destroying bots, but at a reduced payout compared to real players.
