I may add one or more of you also. Have never played any MP or co-op on any game. Would like to start out with some Guerrilla mode. Have played enuf of this mode by myself (and had a good time with it), but can't advance without some teamwork, especially on Veteran or Elite. Maybe work into some co-op or MP, as long as team mates are mature noobs just looking for fun, and open to doing some on-line mentoring.
One drawback I have is available time, when no one is home, and TV is open for a few hours. Usually easiest when wife works night shift, and kids are busy with friends, but that doesn't happen real often.
I have a headset, I *think* it works okay, but won't know until I am on-line for first time.
My GT is JaySTeeY, keep an eye out for my friend request.
