How to unlock the Master Gatherer achievement in BioShock 2 - Definitive Guide

If you want to get this achievement fast, but not pass up on any achievements (savior, for instance), there is still a way. After rescuing your fourth little sister ( in siren alley if you have been rescuing all of them), you get your first gift from the little sisters. Inside is some ADAM, money, and the gene tonic Proud Parent. KEEP THIS ON AT ALL TIMES! It will net you 40 more ADAM per little sister (120 from gathers instead of 80). This will help you out very much in the long run, especially with the Demanding Father tonic that speeds up harvests by 2x.

My point exactly, thank you for agreeing with me!

Yes, defending the sister while she gathers can be a bit of a grind, and can cost you a lot of resources (ammo, health packs, eve, money to replenish said items), but it gets a LOT easier once you get the Demanding Father tonic. You'll probably get that tonic around the same time you get this achievement, so you may be thinking about skipping the ADAM gathering going forward. But it goes a lot faster with Demanding Father, plus you're getting extra ADAM with Proud Parent, so they make it worth your while to continue gathering.

This really isn't too difficult to get.
You go through the little tutorial-ish-thing telling you to Hold X and follow the line, protect them while harvesting etc.

After you finish doing that, you have the ability to do that with any little sister you adopt. Do it enough and you'll get it. It doesn't matter if you rescue or harvest the little sisters only that you collect with them.

Just note; you don't have to collect with them. So if you really don't feel like doing it anymore after getting the achievement you can either harvest them on the spot or adopt them, take then to the vents, and choose to rescue/harvest them there. Having them gather/collect/what-ever-you-wish-to-call-it just gives you a higher ADAM intake.

Always up to you.

I'll add that if you harvest with every little sister from the beginning of the game you should get the achievement in Dionysus Park.

Once you adopt a Little Sister you can set her down next to glowing bodies to collect ADAM. A Little Sister can gather 40 ADAM from each body or 60 ADAM using the "Proud Parent" tonic.

Basic Gathering
As you start out you will need to harvest two bodies with each sister until you earn the "Proud Parent" Tonic.

8 Sisters with 2 bodies = 80 ADAM, 80x8=640

Proud Parent Tonic
You will be rewarded with this tonic after saving four Little Sisters. This will allow you to collect 60 ADAM per body rather than the previous 40 ADAM. If you harvest your sisters after gathering you may miss out on this tonic.

5 Sisters with 2 bodies = 120 ADAM, 120 x5 = 600

Depending on if you use the tonic or not you will earn this achievement either before or around Dionysus Park.

You can either use your map to find the ADAM or you can hold down the for a second and a trail will appear. This will lead to you the bodies that can be harvested.

Note: Saving/Harvesting a Little Sister does not count as a gather. Make sure you gather with each sister twice to avoid missing out on this achievement.

To unlock this achievement you will need to gather 600 ADAM during the Gather sequences. To be clear, this is specifically to 'Gather' the ADAM when you have adopted a Little Sister and not just a cumulative amount of ADAM earned.

See "Dealt with Every Little Sister" above for more details on gathering.

I didn’t fully understand how they counted, but when I had 600 units, they didn’t count the trophy for me. They counted it later. Probably the only thing that counts is that the sisters physically pump them out of corpses - HZ. In general, if you go for platinum and save all the sisters, you will get it anyway

It only counts the ADAM that the little sister collected. You will be able to collect it before the middle of the game. You can spend it right away rather than saving it. And so they will count.

If you purposefully collect all the sisters, they will drop out in any case, whether you save them or kill them.

The trophy is not cumulative. You need exactly 600 units in your pocket.

Not true. The trophy is cumulative. As soon as my sister pumped out the adam, I immediately poured it into Gatherers Garden.
Got a trophy in Siren Valley.
