If the player is killed, they are revived via "vita-chambers.  ADAM can be used to upgrade the player's plasmids and tonics. Lamb sends Splicers and armored "Big Sisters" to stop Delta, to no effect. Many of the weapons and plasmids from BioShock return, as well as new ones like a chain gun and the Aero Dash plasmid. If Delta harvested all of the Little Sisters then Eleanor will extract Delta's ADAM and become bent on world domination, the weather becoming dark and stormy as the corpses of Rapture's inhabitants float to the surface. This Big Sister was written as a Little Sister who, as she grew up on the surface, could not leave the memory of Rapture behind and eventually returned. To test how the music fit for each level, Kamper would send Schyman video footage of the game, which would then be appraised with the new score to see how well it meshed. BioShock 2 begins on New Year's Eve 1958. It is packaged in a 13 by 13 in (33 by 33 cm) case with special art on both the slipcase and the box cover. "This allowed us to quickly iterate on our ambiences and implement them into the levels with ease, and helped create the randomness I was looking for in the background effects", Kamper recalled. These side stories are related to the main BioShock 2 story but remain distinctly individual.  A Special Edition of the game, which was limited to a single production run, contains the game along with three posters featuring fictional advertisements from Rapture that reveal hidden messages under a black light, the orchestral score from the game on CD, the orchestral score from the original BioShock on a vinyl 180g LP, and a hardbound, 164-page art book. ". Hey guys, I'm just wondering if Bioshock 2 is not going to be as long as Bioshock 1. Multiplayer sounds were handled by Digital Extremes, who along with Kamper's team had to make sure their sounds cohered not only with each other's work, but with the sounds of the first game.  The developers wanted to bring some of the mystery back to the location of Rapture, and maintain a balance of surprising old players while introducing the setting to newcomers. He concluded with "BioShock 2 eventually becomes the sequel I hoped for, but spends too much time getting there. If Delta rescued all of the Little Sisters he will die in Eleanor's arms, the weather will be sunny and clean, and she will absorb his personality and memories and leave Rapture with the Little Sisters to change the world for the better.  The first DLC, the Sinclair Solutions Test Pack, was released March 11, 2010. Taking on the role of other Big Daddy models, players engage in familiar activities or explore undiscovered parts of Rapture. " The other major change was that the player's character, Subject Delta, is no longer the first Big Daddy, but rather the fourth prototype. The reason for the change, as explained by Zak McClendon, lead designer for 2K Marin, is "If you have a single character that the player knows they can't kill because they're so important to the story you're completely removing the triumph of overcoming that encounter with them. He is, however, the first to be successfully 'pair-bonded' to a single Little Sister.. Face off against the new Lancer Big Daddy, the most advanced Protector that Rapture ever produced.  The player will also encounter security systems which can be hacked through a mini-game; this requires the player to stop a quick-moving needle one or more times in the correctly colored areas of a gauge. "Bioshock 2 specifically asks players to question all sides of debates when extreme stances are taken, and asks players to weigh their decisions in an alternate and complex history. Only a single sound designer had worked on the previous BioShock's lauded sound, which Kamper called "intimidating"; "we were all basically coming into the project as fans of the first game." In contrast to the first BioShock's focus on libertarianism and Ayn Rand's philosophies, BioShock 2 focuses on collectivist ideals. , The final BioShock 2 DLC was Minerva's Den, released on August 31, 2010. , A remastered version of BioShock 2 (along with Minerva's Den) was released as part of BioShock: The Collection for Microsoft Windows, PlayStation 4, and Xbox One in September 2016, as well as a standalone update for existing Windows owners. Initially there was only going to be one Big Sister who would continually hunt the player down throughout the course of the game and then retreat once she was defeated. " The game uses Unreal Engine 2.5. Which in some respects surpasses my original in my opinion. "As this sequel is an extension of the first game's storylines and characters, there are direct contrasts between the extreme politics of Andrew Ryan's objectivism and the extreme religion/politics of Lamb's collectivism", he writes.  As the player progresses through the multiplayer experience, new weapons, tonics, and plasmids are unlocked, in addition to the story-related audio diaries available in the player's apartment. What's most amazing and surprising about BioShock 2, however, is that by diving deeper into Rapture's tortured history and exploring more of Rapture's haunted world, it actually manages to make the original BioShock better, too. :8 Character concept artist Colin Fix recalled that while the teams researched the time period for era-appropriate influences, costumes would need regular adjustment.  However, a later statement from 2K spokesman Charlie Sinhaseni clarified that the Sea Of Dreams title was for the trailer, and not for the game itself. " IGN's review also stated that the game does not look as visually impressive as its predecessor, but it is still one of the best-looking games around because of its unique art style. And that was me taking my time and checking everything out and not just beelining straight for the goal. "[The artists] had an earlier version of Stanley with a swanky Hawaiian shirt that was in the time period, but felt out of place in Rapture. Bioshock 2 took me about 9 or 10 hours. Another aspect was the choice to harvest or save Little Sisters; by allowing players to adopt the Little Sisters before deciding their fate, Thomas hoped it would help players form a bond with the characters and think about their choice. Also released alongside the Rapture Metro Pack were additional characters and a new game mode. "I really wanted the ambience to sell the fact that Rapture was constantly falling apart around the player", Kamper recalled. Seek out the tools you'll need to unlock new goals and spaces in the order you choose. ":14 Starting with the recognizably human silhouettes of the splicers established in BioShock, the artists decided to push into more varied forms. Minerva's Den offers a brand-new, self-contained BioShock story, presenting a side of Rapture you've never seen before.  The BioShock 2 Rapture Edition is available in Europe, New Zealand and Australia, in addition to the BioShock 2 Special Edition. The first major details on the gameplay and plot of the game were revealed in the April 2009 issue of Game Informer magazine, around the same time that the "viral" site "There's Something in the Sea" was revealed. "Similar to the first game, we tried really hard to instill a sense of thematic cogency with our picks that the message that is coming through the licensed tracks," Thomas said, adding that blues and religious music were important to the sequel's themes, and that while the first game had used more commercial pop music, they wanted a broader range. Delta arrives at the containment chamber where Eleanor is held, but Lamb captures him and severs his bond to Eleanor by temporarily stopping Eleanor's heart. Gamasutra state a possible reason for the Xbox 360's greater sales was the original BioShock's 14-month exclusivity on the platform.
