Very misleading description. This achievement is not on the level New Alexandria. Exodus takes place in New Alexandria, and the achievement is gotten in Exodus, and it isn't clear as to what exactly you need to do, but I believe it for looking at all the dead bodies at the beginning of Exodus, and the teddy bear backpack next to them (the "grizzly scene"). Load up the level on easy from the very start and sprint down to the door at the bottom of the hill. Before going through, look around at all of the dead bodies on the ground. Make sure you look at every single one just to be safe. You will see a small teddy bear backpack on the ground to the left, look at this backpack as well. In order to get the achievement to unlock, I then had to go through the door, kill the skirmishers at the top of the stairs, and look at the dead bodies at the top of the stairs. In doing so, the achievement should unlock.
