[[PennyCrusHer M.I.A]]

Ok so I started killzone online like five days ago or so, and I just got a usb keyboard. I know how to type in the lobby and stuff. Thats quite obvious, but I can't figure out how to type during battle. I know you can type in the scoreboard screen, but when I'm playing someone will will type something and it will come up on the screen where it tells you who killed who. That's what I need to learn to do lol
Please help me lol
P.s. You can add me at your will, I'm free to be pwned.

Ya you cant type durin gameplay, you just have to press select and then your message appears to every1 else that is playing. So when u press enter every1 else sees it where the killls are posted in the top center. Ya im kinda new 2 so you can just add me. And ya u might wnan buy a mic 2
