I am a really big fan of BioShock, especially the 2nd game and Infinite. I know that Irrational disbanded and that there is a very very small chance of 2K making a new BioShock, but I'm still hopeful for one. I also feel if they DO make one, from their own ideas or from fans, it should continue the BioShock 2 storyline since I feel it hasn't been 'completed' like BioShock Infinite was. Pretty sure a lot of other people have done this too, but I came up with some of my own ideas for a BioShock 4: Sea of Dreams (I know the chances of BioShock 4 are very small, but I'm still hoping for one).
My idea: You play as Eleanor Lamb, about a year after the events of BioShock 2 (Eleanor absorbing Delta's memories in the good ending) and Minerva's Den (the cure for ADAM). Basically, you have to go back to Rapture guided by Porter, Tenebaum, and what's left of Delta to cure the rest of the Splicers, Big Daddies, and maybe a new generation of more mutated Little Sisters. I also think that some new opponent, who desires power unlike Sofia Lamb, revives Fontaine and injects him with a 'new' kind of ADAM that makes you much more powerful and is dark purple-black. (Just putting that idea out there.) He and this new opponent are your main enemies, and you must travel back to Rapture (and maybe Columbia), get the materials needed to administer a cure quickly, and cure the Little Sisters, neutral Big Daddies, and the Splicers who still have some sanity left and/or aren't on the enemy side.
Thinking about using new Plasmids like Teleportation, a modified version of Parastitc Healing (deleted Plasmid), and 'remade' Vigors and Burial at Sea Plasmids. You start off with your Big Sister standard weapon and can pick up both Rapturian and retextured Columbia weapons. You also have to face several enemy Big Sisters.
That's my fan idea for a possible BioShock 4 so far. I doubt anyone will respond since this wiki isn't very active because there isn't a new BioShock/BioShock news, but I would still like to hear other people's ideas. Thanks 76.171.143.251 19:30, December 26, 2015 (UTC)
Edit: (No one probably cares but I'm gonna come up with more ideas and post them here just for fun/in case 2K IS making a new BioShock and needs fan ideas) I also came up with the idea of facing Elite Big Sisters with a modified arsenal, 30% more health, different colored armor/equipment, and with 70 ADAM on their corpse instead of 40. Also, as Eleanor, you have to chase and hunt down Big Sisters who are kidnapping Little Sisters from Rapture, an alternate version of Columbia, or even the surface itself.
