Any PS3 users play Call of Duty 4 online?

If you do, what rank are you? (Did you go into prestige mode yet?)

As of now, I'm rank 35. I rarely play, but still an ok rank. I have not got to prestige yet.

I have never played that, I actually have no idea how to do so..

What do you mean? Like how to get online? Or how to like do the controls or what? I'd be happy to try to help if it doesn't involve setting up online connections and stuff, but about the actual online game.

the controls and stuff, I never really was good at shooter games. Is it first person?

Yeah first person shooter. Basically the controls are:

Move- Left Analog Stick
Look- Right Analog Stick
Shoot- R1
Aim Better- L1
Special Grenade- L2
Frag Grenage- R2
Reload- Square Button
Crouch- Circle Button
Jump- X Button
Cycle Weapons- Triangle Button
Sprint- L3 (pressing in the left analog stick)

I believe that's the controls. If you have questions, ask away.
