There is one final secret achievement that requires the bonus downloadable content.

After becoming a Big Daddy, make a new saved game. At this point you are near the end of the game. If you missed something you can go to the bathysphere and explore Rapture again, but also you are a Big Daddy now so the splicers will not harm you, security cameras will not set off alarms, etc.

If you are up against a stationary security robot (RPG, etc.), use Telekenesis to grab a crate or pallet. Hold it in front of you until you can find a place to hide and plan what to do next. The item you hold up will block some attacks.

When fighting a Rosie, use armor piercing rounds from the machine gun or pistol. For a more effective way of killing, launch frag grenades and run out a door. The Rosie will follow you, fire proximity mines at the door, and when it walks through it will be damaged or destroyed.

After hacking a robot, it will begin firing at your enemies. If the robot gets hit it will begin to lose health, catch on fire, and eventually blow up. To stop this from happening, deactivate the robot, then reactivate it a few seconds later. This should make the robot have full health again.

Save the game before you start playing. Just keep reloading the game until you hit it.

1: In Peach Wilkins' hideout (Neptune's Bounty), bottom floor. As soon as you come downstairs it is directly in front of you.

2: On the way to Farmer's Market in Arcadia, the station is located to the left after you go up the first stairs coming from Tree Farm.

3: The Winery's basement in Farmer's Market. There is a flooded area with one of them attached to the wall. It is in front of you when you come down the stairs; just keep going forward.

4: In Fort Frolic, from the Atrium bottom floor, go towards the bathrooms. Then, move right and follow the path until you see some small stairs to your right leading up to a door. Go inside then go down into the basement. The basement is filled with cigars and the like. The upgrade station is on the wall.

5: Go to Poseidon Plaza in Fort Frolic. Go to the other end of the bottom floor (the opposite end of where you enter). Go into Sinclair Spirits (the room that has a corpse on a sort of "altar"). In the basement of this store is the station.

6: In Hephaestus Core Room, go down to the bottom floor and run around (literary). Eventually you will see it attached to the wall.

7: In Hephaestus, Kyburz's office. It is attached to the left wall (back turned to the entrance) in the rear of the room.

8: At the bottom floor of the Mercury Suites area, on the back of the center pillar.

9: In Sander Cohen's secret room, in the Olympus Heights' Mercury Suites area.

10: Go to Atlas' Headquarters in Apollo Square (Fontaine's Home For The Poor area). It is located on the fourth floor. Go down the stairs in the room and look to the right. The station will be in front of you.

11: When you enter Point Prometheus and chase Fontaine, eventually you will end up in a little square and Fontaine will go behind a locked Museum door. At the opposite end of this square (from where you came) is a dead Big Daddy. Next to it is the upgrade.

12: In the Voice changing labs in Point Prometheus, one of the labs has it.

To get the good ending, you must RESCUE all little sisters. Harvesting at least one of them will still yield the Bad Ending.

While under heavy fire from those security bots or if you wanted to avoid getting seen by the camera, short them using Electric Shock. You will have a few seconds to run to the bot and hack it. Once hacked, it will defend you from splicers as well.

When reaching for distant items using Telekinesis, press the X button to drop it to the ground, instead of hurling it away.

On your way to the female doctor's house, [can't remember name], you will walk down a long subway tunnel where you will encounter 10-15 splicers, continue on, and you will be in an apartment plaza, as soon as you enter this area, veer to the right and enter the first door you see, Cohen will greet you with a message and tell you that this is his house, walk forward and you will see a couple dancing, he will tell you to leave them be, of course, theres a point in every gamers life where you just don't listen. Take out your crossbow and walk over to the couple, switch to the "trap" bolt and walk up behind one of them, when you have a clear shot, load a bolt into one of their heads. Heres a bit of a challenge if you're on the Hard difficulty, they are both Houdini splicers, teleporting every which way. Finish them off, to get another message of Cohen yelling at you, he will tell you he is coming down and that he isn't happy. Run back to the entrance and turn around, to face the house again, keep your view to the right, and watch as Cohen opens a door and comes running at you, he is also a Houdini splicer and a mad one, too. Finish him off, and go over to the door he entered from, walk up the stairs into a dark purple room and...

*Note* It is only 10G, but it's also something to brag about to your BioShock buddies who don't have this one!

Get to the point when you reach the medical pavilion and must unlock the doors. When you pull the first switch and go to the second, pull it and Atlas will say "Now you have stirred the Wookie cage".
