Oh, you are well ahead of me as my son and I are doing it on the easiest level!
Took us a while to get through the RPGs. It actually needed 2 of us because the second one is a pest and hard to spot where it is coming from.
Defending Natalya is slightly easier with the right weapon, some aim better than others although you still have to make sure every shot counts though.
We have just made it outside. I guess that we must be getting close to the end.
Have you tried the multi-player stuff yet? I did and I got wasted. I did get one kill in though, so I was chuffed 😆
