How to unlock the Not A Rabbit achievement in Metro: Last Light Redux - Definitive Guide
There is only 1 place in this mission where you can take damage which is outside on the ground level when you go up the storm drain with Anna. Once you reach the courtyard, listen to Anna's instructions and take out any enemies from a far distance whenever possible and make sure to not take damage. If you do "Load Last Checkpoint" and try again.
Upon, completing this area, you will be asked to chase the dark one to conclude the level and the achievement will unlock.
After helping Anna get into position, continue forwards out into the the swamp-like area. Once you drop down a small embankment, three to four waves of three Watchmen will spawn and ambush you. Make sure to strafe back and forth and unload your magazine on them before they have a chance to close in on you. This area is large and open, so moving around will definitely reduce the risk of getting hit as Anna snipes the Watchmen and weakens them.

If at any time you do get hit and mess up, you can always reload the checkpoint and attempt the achievement again. Once this fight is over, all you have to do is follow and eventually “capture” the Little Dark One for the level to conclude. The achievement will unlock during the ensuing cutscene so long as you did not get hit by any of the Watchmen throughout the mission.
This is easier than it sounds, just take an automatic weapon such as an RPK. After Anna takes up over watch, you will jump down into an open area. Some watchmen will spawn across from you. Anna will shoot some of them and you must keep them at bay. If you get hit just restart the checkpoint. For those who need a video guide, here's one by ne1082:
