How to unlock the Little Sister Savior achievement in BioShock - Definitive Guide

This is quite easy. Even though you only get about half the adam you would from harvesting them Tenenbaum gives you gifts after every few sisters including some of the adam you missed out on.

In the long run I NEVER needed that much adam, even without harvesting any little sisters I got the Tonic Collector and the Maxed All Tracks achievement in the same playthrough. (though I did deal with all little sisters as well)

You do not need to deal with all the little sisters, just not harvest any. I would suggest saving before you hit the rescue button just in case you mess up. It may not happen, but wouldn't you hate having to go through the same part twice.

This will not unlock until the final cutscene is over (or that's when it did for me anyways.) So don't get to nervous if it doesn't unlock immediately. If it hasn't unlocked by the time you return to the title screen then I would worry.

EDIT: Thought it might be helpful to give my tips for killing the Big Daddies so here a link to my guide for dealing with all the little sisters

I would reload a save before the big daddie to be safe.

If you take too long to kill a Big Daddy then the Little Sister will run away and you'll have nothing for your efforts other than the items you get from the wreckage.

Is their a guide for finding the little sisters or do you automatically run into them?

@Heavens Twin- It is not hard to find the little sisters, just find a big daddy and follow them to a vent, there is not a specific location that the little sisters start at, or end at, they can be at any location on the level wandering around.

As I said, just find a big daddy and follow them into a vent, that's the easiest way to do it.

My only confusion with me currently tracking down the sisters is that I've killed every big daddy and rescued every little sister in neptune's bounty, but its saying I don't have all of them. is this a glitch? There are still big daddy's walking around but no little sisters, and i see these big daddy's knocking on vents, but nothing comes out.

There is a 'little sister' glitch that sometimes occurs (it happened to me on 'Fort Frolic' I think the level is... the one with the stupid guy and his paintings). I rescued 3/3 little sisters then another appeared in the main area with the paintings and 3/4 showed up on the pause screen. I rescued the sister and got the ADAM for it, then when leaving the area it told me I hadn't dealt with them all. I had no choice but to ignore the warning and continue. I still got the achievements when I finished the game. Thought I would share this in case anyone else runs into this glitch.

One tip for daddy's is to constantly circle them to minimize damage and use best tip ammo for your crossbow. Works like a charm.

This isn't so much a total solution as a great recommendation. The one thing I learned to help defeat the Daddies is to have them fight themselves. Be sure to get the Hypnotize Big Daddy tonic - it is given to you from Tenenbaum after saving only a few little sisters. While you have one Daddy hypnotized and by your side, find another with a little sister, shoot him, and then run away. The two will fight till one dies - you can stand a distance away and finish them both off with heat seeking RPG's or Electric Gel. You get the loot off of both and the little sister without too much effort of a Daddy battle. If the one you attacked survives the battle, be sure to finish him off - he will come after you. His health will be low so you can kill him pretty easy.

Try to save before you fight each Big Daddy in case you make a mistake. Once the Sister's Big Daddy is dead, you can either Harvest or Save them. To get this you have to save every sister on each level by pressing  when prompted with the choice. To see how many sisters are on each level, hit the start button and look for how many icons are at the bottom of the screen.

Note that this will not unlock until after the game is over.

This achievement is highly missable!

This achievement is for rescuing every Little Sister in the game. If you are following this guide, this is the recommended method in order to unlock additional achievements such as “Tonic Collector.” Once you have dealt with the Big Daddy guarding the Little Sister, approach her and press in order to rescue her. If you accidentally Harvest a Little Sister you must reload a save or you will not earn this achievement.

For additional information regarding Little Sisters and Big Daddies including locations, please refer to the “Dealt with every Little Sister” achievement.
