Mumble is an open source voice chat application, that lets you talk to players in realtime. It can also be used in a similar way to IRC.
Set up the voice chat feature using the wizard, which appears first time, and can be accessed in Configure - Audio Wizard.
After installation, you can connect to the worms server here: mumble://worms2d.info/
If the link doesn't work, you can add the server to Mumble manually. In custom servers, add the following:
- Label: Worms
- Address: worms2d.info
- Port: 64738
- Username: (your nickname)
- Password: (no password)
- Enter a password of 8+ characters to register
Click Add, then Connect.
