Story Progression

BioShock 2 contains 38 Achievements and Trophies that you can unlock, but doing so will require at least two playthroughs, with one on the hardest difficulty.

The following Achievements/Trophies are unlocked through completion of the single player story. The following section does contain spoilers, so consider yourself warned! You can unlock each of these bonuses regardless of difficulty setting and your use of Vita-Chambers, and regardless of how you decide to deal with the Little Sisters and the choice characters you encounter.

Icon	Title	Points	Trophy	Description
	Daddy’s Home	10	Bronze	Found your way back into the ruins of Rapture. Make your way through the Adonis Luxury Resort and across the sea floor to the Atlantic Express Depot. Acquire the Electro Bolt plasmid and the Rivet Gun and fend off the brief attack by the Big Sister. Follow the Big Sister to the banquet room where she’ll smash the glass and flood the area. Continue north to the airlock beyond the cliff.
	Protector	20	Bronze	Defended Tennenbaum’s train from Lamb’s Splicer attack. Hack the Security Camera and Health Station outside the gates and set a number of Trap Rivets throughout the lobby in preparation for this battle. Lure the first wave of Splicers into the lobby towards the Trap Rivets. Head into the train station proper and lure the second wave towards the Security Camera to enlist the help of a Security Bot.
	Sinclair’s Solution	20	Bronze	Joined forces with Sinclair in Ryan Amusements. Fight your way through Ryan Amusements to adopt a Little Sister and help her gather the ADAM needed to purchase the Incinerate! Plasmid. Put this fire-throwing Plasmid to use back at the train station, and melt the ice blocking the train’s progress. Ryan meets up with you after you throw the train override switch. Fight your way onto the train and take a ride with your new partner.
	Confronted Grace	10	Bronze	Confronted Lamb’s lieutenant in Pauper’s Drop. Make your way to the top floor of Sinclair Deluxe Tenements and enter Apartment 307. Tear down the poster of Sofia Lamb and press the hidden button inside the wall to reveal the secret room where Grace is hiding. Approach the window to have Grace open the door, then go inside and get the Override Key.
	Defeated the Preacher	20	Bronze	Defeated the Preacher. Make your way to Pump Station No. 5 on the eastern side of Plaza Hedone in Siren Alley and take out “Father” Simon Wales. Although he’s taken the form of a Spider Splicer, he possesses roughly 600% the health of one. He also has a Security Bot under his command that you’ll need to turn against him either by hacking it or by hitting Wales with Security Command. Use Rocket Spears and Anti-Personnel Rounds to bring down Simon Wales. A Mini-Turret definitely helps as well.
	Nose for News	20	Bronze	Discovered the truth about Dionysus Park. Stanley Poole has cut you a deal—he’ll override the controls and allow you to continue on from Dionysus Park in exchange for dealing with the three Little Sisters that have returned to the area. He doesn’t care how you do it; just defeat the Elite Bouncers that protect them, then either rescue or harvest each of three. These Little Sisters carry with them memories of what led to the park’s eventual flooding.
	Found Lamb’s Hideout	20	Bronze	Gained access to Lamb’s stronghold. Collect the four ADAM-infused plants scattered around the ADAM Research Laboratory at Fontaine Futuristics and insert them into the Sea Life Tank containing Gil Alexander. Fend off the enemies that attack and use the controls to extract a genetic sample from Gil, then retrieve the key. Return to the seafloor and insert the key into the hidden slot on the OxyFill Station pump. Use the elevator beyond the Airlock to enter Persephone, Lamb’s hideout.
	Reunion	50	silver	Reunited with your original Little Sister. Control the Little Sister in Persephone and gather up the three Big Sister suit parts. Bring them to Eleanor in the Quarantine Chamber so she can break Subject Delta free from the Examination Room. Take the Summon Eleanor Plasmid from her to complete the reunion. Now you can be with her whenever you want.
	Heading to the Surface	25	Silver	Headed to the surface on the side of Sinclair’s escape pod. You’ve succeeded in helping Eleanor free the Little Sisters from the Pediatric Wards and boil off the water in the vessel’s ballast. You made your way down the hallway to the Docking Tunnel after flooding the Docking Platform and completed the game.
	Escape	100	gold	Escaped Rapture. This bonus unlocks during the final cinematic, providing you with one more award for completing the game. It luckily unlocks regardless of difficulty setting or how many times you died.
