Ahoy, online gamers!
If you are used to play online real time games, you must use some kind of VoIP client, and chances are the chosen one is TeamSpeak.
Well, good news! TeamSpeak 3 has gone free for a limited time (until December 23rd), so now you can talk to your buddies directly from your device!
The app is fairly simple to use, with the usual options (push to talk or voice activation), so if you use it on your PC, give it a try on your mobile device (at least install it before the price goes up again).
TeamSpeak 3 is universal and, as I said, FREE for a limited time.
