2 hardest parts in crushing are the plane wreck and the water room.
Both took me over 1 hour each.
The rest of the game is relatively easier after that.
One possible remaining hard part is the fight outside the church toward the end but I used a trick.
I came loaded with the sniper riffle from the previous stage ( had 7 bullets) and after killing the first 2 guys you see that were shooting at my buddy I ran back the way i came from and sniped all the guys coming at me..
It made that part a lot easier as otherwise you can be stucked under crossfire with limited cover...
But yeah crushing can be a bitch...
I got one shot by a shot-gun blast fired like 20 yards away from me........
