Sniper Elite 4 Allagra fortress Authentic Plus difficulty without taking any damage pt 1

You can pretty much run to the third bunker below the fortress without taking any fire - though doing that you'll have more enemies hunting for you and it makes a no damage run a bit harder.
I show the route in my other A+ runs.
To take no damage I prefer to take out as many enemies as possible to save being ambushed further along - clearing out an area before progressing means you have a safe place to run to if you need to and keeps your back safe.
Though SE4 does have a habit of putting enemies exactly where you are if you need to retreat!
I also take the opportunity to stock up on traps too - you'll need them in this level as they are amazing for keeping enemies off your back and thinning numbers down.
Trap placement in the fortress is key to getting through the level on A+ difficulty.
