Yeah it's nearly impossible on the hardest difficulty, but I found a trick that may help you. In the last battle in that room where after you go down those stairs, try to hang on the stairs and crouch to kill as many as you can. Run back up the stairs if the fire coming at you gets to heavy, or have fun bouncing grenades from the stairs into the room. Just do as much damage from there as you can before you go in, because once you do, the door to the stairs will close on you. Anyway, after it does, STAY IN THE DOORWAY to the stairs. From there, you have to take out the first wave, then move your your position to the right/left corners of the room (right by the door) and fight from there. It's hard as hell, but the most important thing is to stay on top of the guys with the RPGs (take them out as quick as you can), mind the shotgun guys, and of course frag the shield/magnum guys.
So yeah. It's tough, but if you do the stair trick and then just keep hopping back and forth between those two corners, you should be ok. The hardest part is when you run out in the open for a health pack and then getting back to your corner. GOOD LUCK, you can do it!! :thumbsup: :hatsoff:
