Sniper Elite: Resistance

This is a relatively easy achievement that I unlocked on mission 2. Now there may be shorter missions after 2 up until 8 that will get you this quicker, but that doesn't really matter. Here are 2 tips to get this achievement on any level 2-8 that you wish.

1. Manually save the game frequently which is done in the pause menu 2nd option down.

2. It says no healing not no dying. If you take a significant amount of damage where you would normally want to heal, just let the enemy kill you and reload the last checkpoint.

I was playing on sharpshooter and died numerous times and this achievement popped after I exfilled using no bandages or med packs.

I hope this helps and if there's any way this guide can be improved, please let me know.

I got this while playing through on level 4.
Just took my time, sniped everyone I could see from start point on bridge and in bunker to the right.
Go down zip line, climb hill slightly then look around again for anyone you may have missed.
Follow path around, take your time and take out enemies, there’s not to many.
Follow path an around again, go into building and carry on taking them out via the sniper. Put some mines at bottom of stairs just in case.
Again, take time, following path around getting advantage points. Observe with binoculars and carry on sniping.
Again, just take your time and I found it relatively easy. I ignored the tank completely.
I did this on sharpshooter level, and pro Took about 40 minutes.
