I'm at about 127 missions or so. My problem is that I spent waaay too long fighting EVERY random battle that appeared because I was wanted to make sure my guys all had as much experience as possible.
Did you get those 298 missions on your own, or did you research how to get all the required mission items you need? I went for the longest time with two missions asking me for jerky that I didn't have, and I know there are a ton of others calling for items I don't have now. I guess what I'm asking is whether or not the items I need will happen to appear, or if I have to *make* them appear.
While I will probably rent Marvel UA 2, it will probably be for PS3 if anything. Now next week...that will mark my return to the XBox console, something I haven't done since the UFC game months ago. Halo 3:ODST!
