To use squad chat on PS3 simply talk into the mic. Unless you are a leader you can only talk in squad chat. Squad chat is however disabled if no one else in your squad has or is using a mic.
yes
Wii fit
either buy a wireless bluetooth mic, or wired mic. connect or plug in the mic and then should be ready to chat :)
yes called voice chat (any mic that connects to your computer should work) can be used in guilds (normal and officer), groups, raids etc
No mic required, text chat by pressing 'y' ('u' for team chat) in game
In your popit click text chat but if you have a mic you can talk through that I do
No, unfortunately not. You have to have your Xbox plugged in, on, and connected to Xbox Live (R) to talk with anyone in voice chat. HotKookies
Yes you can if you have a mic to chat with people by voice.
You can use it as a mic, video chat with friends, or take pictures with EyeCreate.
If you are refering to online chat support then I'm afraid that is not possible. Goldeneye 007 for the wii does not support any online chat.
No. If you dont have a mic or just dont want to talk disconnect your mic and go to settings and turn off chat sound that way the voices wont come through your tv.
