BioShock 2

In February 2010, 2K Marin released a sequel set eight years after the end of the first Bioshock. In this new game, the player is the Super Prototype Big Daddy "Subject Delta". Delta wields plasmid abilities and some nifty new tools as he attempts to track down Eleanor, the Little Sister with whom he was originally bonded. There's a new, very dangerous enemy called the Big Sister, and another romp through Rapture, now run by Andrew Ryan's collectivist foil Dr. Sofia Lamb. All accompanied by another Viral Marketing campaign.

BioShock 2 includes a multiplayer section, where players take control of Splicers during the war and compete in games like Deathmatch and Capture the Flag. Winning these games rewards the player with ADAM which is used to buy new weapons and plasmids. Players also got an apartment, where they can change the appearance of their Splicer.

In August 2010, 2K released two DLCs for Bio Shock 2: The Protector Trials and Minerva's Den. In The Protector Trials Tenenbaum activates another Alpha Series Big Daddy and asks him to save several Little Sisters from Sofia Lamb. Minerva's Den follows another prototype Big Daddy "Subject Sigma", who is tasked with obtaining a copy of Rapture's computer mainframe, called The Thinker, by one of its creators Charles Milton Porter. The latter is an actual story, while the former was a series of challenges with limitations, like using only certain weapons or plasmids.

The base game contains examples of these tropes:
"Sinclair: I'd say he's hiding something but he sorta took the fun out of that one."
 * Action Girl: . She is awesome.
 * All There In The ARG: Didn't follow "Something In The Sea?" Then you have no real concept of a) who Mark Meltzer is, b) why you should care, or c) why he was awesome enough for fans to demand he appear in Bio Shock 2.
 * Amusement Park of Doom: Ryan Amusements. Already a nightmarish propaganda tool, by the time you visit it in Bio Shock 2, it's just another urban battlefield strewn with lurking Splicers and automated gun turrets.
 * Art Shift: In the original, the Splicers' character models are a little messed up but still seem human. The sequel takes place about a decade after the original, so the Splicers have been mutating even further for years, and many are half-feral by this point. As a result their character models are much more exaggerated, with giant tumors bulging out of their clothes, and even hooves and talons on some of them. Meanwhile, the Little Sisters were changed from their Creepy Child models to ones that evoke our paternal instincts better - there's even a difference in their reactions to being saved. The Little Sisters in the first game near-tearfully thank you, but the ones in the second act as if nothing much happened.
 * Although this could be because in the second game you play as a Big Daddy, so they may be already used to this kind of treatment, but from a humanoid figure, they maybe more thankful for your kindness for rescuing them when it's not actually necessary.
 * Apologetic Attacker:.
 * Be Careful What You Wish For: Fans wanted to see Mark Meltzer's story come to a definite conclusion, so 2k Games put Mark Meltzer in the game
 * You don't have to kill him. There are several other Big Daddies around. Although if you don't, he will most likely.
 * A smaller example for assuming you're rescuing the Little Sisters:
 * Book Ends: The game ends outside the lighthouse where the first game begins.
 * Can't Live Without You: The Alpha Model Big Daddies (including the Player Character of the sequel) will either go in a coma or die if they're too far away from their Little Sisters.
 * They later clarify that most of the Alpha Series died or fell into a coma; some did survive, but were driven insane, filled with such homicidal rage and despair that they're barely useful to their creators as footsoldiers.
 * Captain Obvious: Lampshaded when Stanley recruits your help to bury evidence of his own actions.
 * Captain Obvious: Lampshaded when Stanley recruits your help to bury evidence of his own actions.

": "If Utopia is not a place, but a people, then we must choose carefully, for the world is about to change, and in our story, Rapture was just the beginning.""
 * Capture the Flag: The sequel's multiplayer mode, "Capture the Sister".
 * Chekhov's Gunman: You play as the Big Daddy who
 * Corrupt the Cutie: Eleanor Lamb is.
 * Country Matters: The Brute Splicer has a potty mouth at times.
 * Crap Saccharine World:
 * Cruel Mercy: The good ending, when
 * Can be considered 's fate. He's stuck in Splicer-infested territory with the only way out leaving, and he certainly can't take refuge in the booth anymore.
 * Cult: Lamb's "Family," complete absolute fealty to their leader, messianic figure, and suicidal "ascension" ceremonies.
 * Cute Bruiser:
 * Daddy's Girl: Eleanor to Subject Delta, much to Sofia's irritation.
 * : in the bad ending.
 * Dangerously Genre Savvy: Sofia Lamb. Once she realizes Eleanor is helping Delta, she sits in the quarantine room with her and watches her every move. Later,  Immediately afterward,   Later, , and then  . Then
 * Darker and Edgier. It may seem impossible, but Bio Shock 2 manages to get even darker and edgier than the first game, at least in some respects.
 * Deflector Shield: The level 3 upgrade for the drill.
 * Distaff Counterpart: The Big Sisters.
 * Dual Boss: There's a Climax Boss fight against two Big Sisters at the same time at the beginning of the final level.
 * Dual-Wielding: Subject Delta can wield a Drill/BFG with one hand and shoot plasmids with the other. Justified on account of his enormous size and strength.
 * Easter Egg: Bio Shock 2's Unstable Teleport Plasmid.
 * Using the Incinerate plasmid in a block of ice in Dionysus Park reveals a cat called Schrodinger...
 * Electronic Speech Impediment: Alex the Great's "secretary".
 * Elemental Powers: Of the standard fire, ice, lightning variety, same as in the last game, along with one wind-based plasmid. Genes can influence your resistances to said elements and also cause you to emit them when struck. And if you enjoy using the drill, you can become a full-on ice guy with the Freezing Drill gene.
 * The End of the Beginning: The best ending

"Danny Wilkins: Tell your sister I said "Hi!""
 * Environmental Symbolism: The vista of 2's ending varies depending on your moral choices during the game. The best ending shows a lighthouse under a stunning sunrise, a more ambiguous ending has a tiny glimmer of sunlight surrounded by a darkening sky, while if you were a real bastard it's a bloody hurricane up there.
 * Evil Counterpart: Inverted. Augustus Sinclair is still an improvement over Frank Fontaine.
 * The Evils of Free Will: The basis of Sofia Lamb's philosophy: that free will and self-awareness are the root of evil, and that only by "killing the self" can one achieve peace. This leads her to create a cult.
 * Firing One-Handed: How Delta uses all his weapons.
 * Flawed Prototype: The Alpha Series can only be bonded to a particular Little Sister, and initially had a penchant for wandering away from them. This resulted in the formation of a permanent bond, so that if that Little Sister is lost, the Alpha unit either is rendered comatose, becomes morose, or flips out.
 * Foil: Sofia Lamb, who believes in original sin, the impotence of human reason, as well as altruism, is literally the opposite of an Objectivist like Andrew Ryan. Some of the audio diaries in the contain snippets of debates between them, an interesting look at two diametrically-opposed forces colliding on stage.
 * Gatling Good: In 2, the Tommy Gun is discarded in favor for a minigun you carry one-handed. Meet your new best friend.
 * Guide Dang It: The sequel's achievement "9-Irony", it doesn't help that its also secret.
 * Give My Regards in The Next World:

": You had me under a gun, and you just walk away? No monster alive turns the other cheek. Ha, no monster does that. (horrified) ...a thinking man does that."
 * Gone Horribly Right: The Alpha Series Big Daddies. The scientists tried to create a bond where the Big Daddies viewed the Little Sisters as their own daughters. It worked - they just didn't factor in the implications of what happens when a father is forced to watch his own daughter get killed in front of him. The Daddies would break down and sob in front of the Sisters' crawlspace entrances, and become only suitable as berserk soldiers. That's why the Big Daddies we see in the game are more of Punch Clock Bodyguards, so that if the Little Sister dies they only lose one asset instead of two.
 * Good Is Not Nice: "Semi-Good" Delta. He won't kill innocent (or even not quite innocent) people unless they truly cross the line, but if he has to harvest Little Sisters in order to get the power needed to save his daughter, so be it.
 * This of course depends on what gameplay choices you make, which are a little more open-ended than in the first game. Delta might choose to save all of the Little Sisters he finds instead of harvesting them. However, given that a complaint about the first game was that you could eventually buy most plasmid upgrades once you built up enough Adam, the sequel makes it impossible to afford all of the plasmid upgrades if you save every single Little Sister, making it a much more tempting choice to harvest them. Further, Delta can choose to actually kill the "not quite innocent" characters he comes across, who are more flawed gray-and-gray morality than actually "evil" people.
 * Harpoon Gun: The Spear Gun.
 * Heel Face Turn:
 * Heel Realization:

"Ryan: I spoke to a young man exiting the park after the grand opening, asking him what, if anything, he had learned here. He said his chores didn't seem so bad anymore - as long as mother wouldn't send him to the surface."
 * Hellhole Prison: Persephone, where many of the inmates were used as test subjects or committed suicide in desperation and sadness after being locked in a tiny prison cell, constantly isolated minus feeding times, with very little to eat. Their crime was speaking out against Ryan, who constantly promotes freedom and minimal government interference in his speeches.
 * Hopeless Boss Fight: The first Big Sister fight is impossible to win, though she'll retreat after you're critically low on health.
 * Human Sacrifice:
 * Impaled With Extreme Prejudice: 2‘s spear gun allows you to do this to your enemies, and it is both quite satisfying and efficient, since you can retrieve the spears and reuse them. If that's not enough, you can have the instrument of impalement gleefully propel your victim around the room, then explode - Rocket spears are your ammunition of choice.
 * Inappropriate Hunger: If you Incinerate! a splicer while carrying a Little Sister, she asks for marshmallows.
 * Instrumentality: Sofia Lamb's ultimate goal,.
 * Ironic Echo: Not the best example, but the  are very similar. Just an inflection difference in two cases.
 * Also the Ryan Amusements. All government activities that are mocked in the main ride (indoctrination, suppression of rights, market control [Fontaine rose to power thanks to smuggling], youth indoctrination etc.) are actually endorsed by Ryan.
 * Jerk Jock: Danny Wilkins in the Bio Shock 2 multiplayer. Also subverted to an extent with Pigskin, the young football player Splicer, who is the most sympathetic enemy model since he doesn't want to kill you, but his boss will kill him if he doesn't.
 * Karma Houdini: In the "best" ending,
 * Also Stanley Poole who, despite being a  could have been be spared by Delta. Of course, he was still stuck in the underwater city infested with homicidal mutants.
 * Karmic Death:
 * Alternatively to Karma Houdini above,
 * Lite Creme: There are various posters for "Beef•e" potted meat, proudly advertising "The taste you remember!" Judging from a Dummied Out audio diary from the first game, it isn't real beef.
 * Make Me Wanna Shout: Subverted. Big Sisters announce their (incoming) presence with metallic screeching, causing the surrounding structure to rumble, but it's not a weapon, thankfully for you.
 * Meet the New Boss: Lamb and Ryan may have had diametrically opposed ideologies, but they both take it to such extremes that both of them effectively become the same person in methods. Ryan doesn't care about his underlings individually because "look out for number one" is his motto, and Lamb takes the "collective good" so far that to her, one person's life is meaningless.
 * Messianic Archetype: Eleanor Lamb is raised to be the perfect creature who is Too Good for This Sinful Earth and so she can be
 * Mind Screw: The unstable teleport plasmid journey.
 * Mole in Charge: Sofia Lamb put Stanley Poole in control of Dionysus Park, her sanctum. He was Andrew Ryan's spy all along.
 * More Dakka: Compared to its predecessor Bio Shock 2 definitely enjoys and employs this with both its weapons and plasmids, especially since you're using both at once.
 * There's the option of summoning two security bots, hypnotizing a Leadhead Splicer or Alpha Series, and laying out mini turrets while firing away with your own Gatling Gun all at once to create a hailstorm of bullets (hacked turrets and security bots summoned by hacked security cameras also possible), playing this trope rather straight and proving rather effective.
 * My Beloved Smother: Probably the mildest example of Sofia Lamb's style of parenting would be keeping her daughter all but a prisoner in her home to keep her from the "dog-eaters" outside.
 * Nerf: Quite a few of the weapons and plasmids were rebalanced/depowered in the transition between Bio Shock 1 and Bio Shock 2, probably for multiplayer purposes or on account of the new dual-wielding gameplay.
 * Obvious Beta: Bio Shock 2's PC version has many minor bugs, and most of the patches go to the multiplayer. Hint: Don't go to the 2K Forums if you don't have a flame-retardant suit on. Although Elizabeth is strictly protective against it.
 * The Pollyanna: When
 * The Trope Namer Pollyanna was written by Eleanor Porter. Coincidence? This combined with Charles Milton Porter of Minerva's Den.
 * Put On a Bus: Tenenbaum. Almost literally, since she hops on an underwater train and disappears from the plot. Minerva's Den shows that she left to help get the Thinker, a computer capable of curing the splicers out of Minerva's Den.
 * Retcon: The second game is naturally built on this, as it delves further into the history of Rapture. (Primarly via Revision.) Particularly obvious examples include the introductions of Sofia Lamb and the Alpha series.
 * Psycho Prototype: The Alpha-series Big Daddies. All except Subject Delta went bonkers after losing their bonded Little Sister, making them quite effective as soldiers but not suited for anything else.
 * Redemption Equals Death :
 * Remember the New Guy: Turns out, Sofia Lamb was out of the picture by the time Atlas was picking up steam, but still a forefront in the "Maybe Ryan's not right" train of thought.
 * Sawed Off Shotgun: Played totally straight with the damage upgrade to 2's shotgun, which literally says sawing off the barrel makes it deal more damage. Precisely why the developers think long-barreled shotguns actually exist is anyone's guess.
 * Scare'Em Straight: The purpose of the "Journey to the Surface" ride in Ryan Amusements is to convince Rapture's youth that all that waits for them up there are authority figures ready to reach down and steal their stuff, quash their ambitions, or drag them off to war. Ryan's a bit iffy about the creepy animatronics, but...

Ryan's a bit iffy about the creepy animatronics, but...


 * Sequel Escalation: An interesting case - the story is equally good, with a villain based on opposite ideals to Ryan, but the combat is Up to Eleven by comparison.
 * Shoot the Shaggy Dog:
 * Shrouded in Myth: Jack's status by the second game. As a nod to the multiple endings, Splicers argue over the specifics of his adventure in Rapture, while one sect views him as a Messianic figure who freed them from the tyranny of Andrew Ryan, and who will return someday.
 * Sliding Scale of Idealism Versus Cynicism: The multiple endings of Bio Shock 2 run the gamut very nicely, with the best ending on the idealism side and getting further down the scale as you go.
 * Spirit Advisor: in the good ending.
 * There Are No Therapists: Actually, Ryan originally invited Sofia Lamb to help people deal with living so far from sunlight, but it didn't go well. It didn't help that the therapist was just as crazy as her patients.
 * Throw It In: "Something In The Sea" wasn't going to have an effect on the main game, but fans loved it so much that protagonist Mark Meltzer was given a minor role in Bio Shock 2.
 * Took a Level In Badass: For most of the second game, Eleanor is set up as the Damsel in Distress. However, that all changes
 * Actually it was her who  and helped him along his way.
 * Pretty much everyone in Rapture is far more badass than in the first game, enemies included. The creators themselves said that Jack wouldn't have survived Rapture this time around.
 * Understatement: In an audio diary from the sequel, Ryan admits that "I...visited Eve's Garden today...it ended poorly." Translation:
 * The Unfought: Despite everything that Sofia Lamb does during the course of the sequel, you never fight her.
 * Universal Ammunition: Bio Shock 2 features the world's first .50 BMG Thompson, so that it could share ammo with the Big Daddy's huge gatling gun.
 * Unseen Prototype: The name Subject Delta implies that there were three before you, and they... well, we don't talk about them.
 * However, an audio diary from Gil Alexander cites Delta as the first successful Alpha Series, so you can probably guess what happened to the first three on your own.
 * Vorpal Pillow:.
 * Well-Intentioned Extremist: The Neutral ending of 2 turns Delta into this - he did what he had to to save Elanor,.
 * What Happened to The Mouse?: Tenenbaum disappears early in the game without a word. Minerva's Den explains where she went, though there was/is a bit of a gap between her disappearance and the DLC. Also, no explanation is given to what happens to the NPCs Delta spare.
 * When fans spoke up about the possibility of not knowing Mark Meltzer's fate after the events of "Something In The Sea," 2K added him to Bio Shock 2.

The Protector Trials and Minerva’s Den DLCs contains examples of these tropes:

 * AI Is a Crapshoot:
 * Book Ends:
 * Faking the Dead: In a sense,
 * Fun With Acronyms: In Minerva's Den, we are introduced to Rapture's Master Computer, the Rapture Operational Data Interpreter Network, nicknamed "The Thinker". If you notice what the acronym spells, the nickname starts making more sense...
 * Instant AI, Just Add Water: The Thinker.
 * In the Future Humans Will Be One Race: An audio log in the Minerva's Den missions reveals that people in Rapture have begun using plasmids to change their race, as Porter recalls a businessman suggest he splice himself white to get ahead. May or may not explain why there's so few characters who aren't of Anglo or Russian descent.
 * Replacement Goldfish: It becomes clear that C. M. Porter attempted to make The Thinker simulate his dead wife.
 * Twist Ending:
 * Wham Line:


 * Xanatos Gambit:
