Nothing that difficult in these levels. Nosalises go down to just a few bullets fired from a Bastard Gun. Revolvers drop them in one shot. Ammo should be conserved wherever possible if you plan on buying the special armour later at Armory (instead of being forced to buy ammo). Use the knife if you're able to.

I edited the user.cfg with notepad in order to increase the FOV.
To do this you must edit the SICK_FOV value in the THREE user.cfg files located here:
C:\Users\[your username]\AppData\Local\4A Games\Metro 2033
C:\Program Files (x86)\Steam\steamapps\common\metro 2033
C:\Program Files (x86)\Steam\userdata\[random set of numbers]\43110\remote
Important: You need to keep the fullstop. I set it to "SICK_FOV 65." Remember that Metro uses vertical FOV measurement rather than the common horizontal measure. A vertical FOV of 65 is a horizontal FOV of 90 on a 16:10 1920x1200 resolution. Setting it any higher might make some errors appear like seeing the 'end' of your arms during reload animations or cutscene animations. You can try to see what you like best.
I just think the default FOV is ridiculous... and unfortunately, this is becoming way to common an issue for console ports nowadays.
