Completed the BRIDGE level without a kill
Metro Last Light Redux RAIN MAN – Achievement / Trophy Guide
As long as you play on normal and sprint for the whole level, you won’t have much trouble getting this. AFTER JUMPING THE SMALL GAP (0:27) at the beginning, stay left and don’t get too close to the watchman there, he can be very persistent when he catches up with you. Use Med Kits if you get hit and you should be fine.
