You don't need to kill everyone. I ran through the whole thing just killing the guys i had to, to stay alive.

 

The best thing to do is to just die a lot and find one way to go then remember where the part you died at before was and how to kill the guy. I found the easiest way to go is to go right each chance you get. Remember the farther you go up concealed the farther up your team goes and kills people for you!

 

Madden 09 FTW!!!!

I suck at these games

 

Definately watch for the points where your guys come up and help and pause there briefly to get your bearings and recover some health if you have to for the next push while they do some of the work. I've had to do this quite a bit on COD5.Sometimes you just have to Rambo it, though.

 

i played it a couple more times last night....got to the staiway checkpoint with like a minute and a half more time, which i was happy with, but its the next long hallway with corridors on both sides with guys camped out to kill you. can't seem to get through it quickly enough, and yet not die. if i take my time i can do it, but when i start to hurry i get wasted.
