*MINOR SPOILERS*

Unbreakable is the name of the achievement. You have to kill the Big Sister.

In addition to Doc Buddha's solution about stocking up on First Aid Kits (which you'll need on Hard Mode because two hits after upgrading health and you're left with a sliver of health) and directions on when you pop this achievement after getting the Incinerate Plasmid, don't forget stock up on Eve Hypos.

Big Sister has 3 attacks that I've noticed (feel free to comment if you've seen any more and I'll put them in the solution) :

1. Melee - she rushes you and slashes you for a lot of damage. This is the attack you want to avoid.

2. Incinerate - A Plasmid attack just like yours but easily avoided if you have some distance on her.

3. Telekinesis - Another Plasmid like yours only she doesn't have to have anything near here to pick up.

I reloaded my save prior to fighting her a couple of times and the easiest way I found to defeat her was Electro Bolt to Stun her and then pop her with Heavy Rivets using the Rivet Gun. Hopefully you've saved some Heavy Rivets, but regular rivets will work. The Rivet Gun in general seems to do more damage to armored enemies than your Machine Gun. If you've upgraded the Rivet Gun's damage, even better (I upgraded the Machine Gun).

There is a puddle of fuel on the floor near the bench in the middle. Be sure to use Incinerate on her while she's in the puddle of fuel. Stunning her with Electro Bolt while she's in the puddle of fuel is a nice tactic to give yourself time to Incinerate her.

Other than that, just keep your distance. Run backwards while circling the obstacle in the middle of the area where you're fighting and always face her. Stun her with Electro Bolt and fire off Heavy Rivet or Rivet headshots. The most important thing of all:

DON'T FORGET TO LOOT HER CORPSE. She carries ADAM on her. If you were short some ADAM and you wanted another Plasmid or Tonic when you visited the Gatherer's Garden the first time, run back and get it (I went back and got Armor Shell because I was taking a beating throughout the entire level hehe).

Good luck and hope this helps. If people have too much trouble with this, just let me know via PM or comments and I'll make a video (which I may do anyway).

EDIT: Guh... I thought I added points and tips from peeps commenting on the solution, but I guess I didn't. Sorry, guys! lol.

Here are some more tips:

"When I fought her she used her telekinesis to pick up rubble. It would spin around her head for a second then shoot at me. I'm playing on Normal and did this on my first try." -blomphil2

"Good points but I like using the drill rush attack, follow up with melee, then electro bolt so you can back up and not get hit running away. Then again I might be a little biased since I upgraded the drill fully, researched some stuff to up the damage, and then use tonics to improve it. lol But it is still pretty powerful." AuraOfRage

Yea, same here, Phil. She had like 3 pieces of debris that just seemed to materialize out of thin air.

AuraOfRage: D'oh! I think I missed a Power to the People then. I only found two by this point in the game. There's a third? Or does the Drill only need 2 upgrades to get the rush attack you mentioned?

Okay, I just reread your solution on protecting the Little Sister, AuraOfRage, and realized you did that achievement a little later than I. So you had Drill Rush and I didn't and it's not a PttP upgrade. I just got the Drill Rush move and now see what you're talking about hehe. I am having so much fun with it, I'm running back through the level just lookin' for a fight!

One other thing: while I would love to have an upgraded Drill (which is next on my upgrade list), the fully upgraded machine gun is friggin' tight. Ricocheting buwetts 4tw! It makes fighting mobs of enemies ezmode especially when guarding the Little Sister.

I just snagged this one on hard mode, and I noticed none of you recommend the method I used..

First of all, it DOESN'T have to be the first one - Big Sisters arrive whenever you rescue/harvest the final Little Sister in an area - so I was pretty late in the game when I got this one. (I didn't know about it)

The key for me was setting a good long passage for her to run through (lined with LOTS of trap rivets) and a room at the end (at a 90 degree angle to the corridor) so you can beckon her to charge through all the bolts, get her into the room (she may hit you once or twice here, be deft and generous with health packs) and get around her, drop a DECOY in the middle of the room and step back out into the corridor. Bring your Speargun to bear and hit her with a few Rocket Spears. Replace the DECOY and Rocket Spear her again.

As long as you're accurate with the Speargun, the rocket spears will do it by themselves (recommend 5 or 6), but if you feel like micromanaging, it's always worth setting her on fire (though the rocket spears do this anyway) and covering her in bees for extra DPS. Using this method, I needed 2 of my 6 healthpacks, and the only time I was in ANY danger was when I was getting around her in the small room. Remember to keep DECOY as your active plasmid as much as possible, because you don't want her to suddenly flip out at you with a rocket spear in her face.

For this achievement you will have to kill the first big sister you come across. You will meet her a few times prior to this fight but she will flee before you get to kill her. This fight is soon after you buy the incinerate plasmid. It caught me by surprise as I wasn't expecting a fight like this out of the blue.

My strategy was to use the Rivet gun. I had already upgraded the damage for this weapon. Along with this I used the electro plasmid so that you could stop her using her lunging melee attack.

What she will do is hang back and fire a few fire plasmids at you, these are easily dodged. Take a few shots at her with the rivet gun and this should take off some health from her. Then after a while she will try to lunge at you. As soon as you notice she is doing this, use your electro plasmid and run back, then shoot her some more with your rivet gun. If you fail to hit her with the plasmid use the gun to hit her by hitting B. Then use the plasmid.

Using this method I lost hardly any health and the fight was quite short. Then loot her corpse!

You will come across more then 1 big sister so you don't need to get it right on the first encounter. You'll get more opportunities later in the game.
