So gamespot scored a hot exclusive on Bioshock 2, which can be read here.

• The game is set 10 years after the original Bioshock.
• One of the rescued little sisters from the first game is a bit screwed up and never wanted to leave rapture. So she goes missing, going back to Rapture and ultimately becoming the 'big sister'. Cue string of kidnappings, which brings the reintroduction of little sisters and somewhat revival of the city.
  
• You play as the first 'prototype' Big Daddy (maybe the last one alive?), which seems to have been in some sort of hibernation for whatever reason, once again reactivated by Dr. Tenenbaum to help out the sisters and sort shit out.
• Apparently the big sister could be working for someone else, who in turn could be working for someone else. Interesting.
• Old locations may be revisted in their aged state, as well as introducing new areas of course.
• Underwater areas outside rapture essentially act as a breather, to take in the views of the city without the threat of splicers.
• Little sisters first act friendly towards you unlike the original, you being a big daddy and all. You have to option to harvest them or adopt them.
• If you adopt them they'll sit on your shoulder and you'll get enhanced vision, being able to see sources of ADAM. If you take them there, the little sister will harvest the ADAM for you to use. Doing so will attract heat from the splicers however, so you'd best be ready to kick some ass and protect her.
• Weapons will include heavier weapons as seen in the original like the drill and rivet gun, though they may be slightly different, as well as new stuff. The weapons can be upgraded too.
• Plasmids have more powerful versions still, but now they can be charged up for stronger attacks and combined too (incinerate and cyclone for instance forms a fiery tornado trap).
• The big sister also makes apparent use of plasmids herself, being able to throw things around telekinetically.
  
• More normal NPC's, who aren't completely screwed up like everyone else, will be present to interact with. There will be some choices regarding these people which can affect the story.
• Throughout the game you'll learn more about Rapture before, during, and after the original game. It sounds like you'll find out about your own origins too; your past life before becoming a big daddy and maybe how that process occurred.

It looks like the Big Daddy you play as is the orignal big daddy, the prototype, who just happened to be a whole lot faster than the others, and has the ability to weild and blend plasmids. Not sure why they downgraded the final model. I also don't think the new moral choice is as good as the previous game. Now, for being good, you get expanded vision and your little sister will gather ADAM as you go along along, so you'll get a whole lot more. The whole kidnapping dynamic seems funny, too. They also allude to a plot twist that twists before twisting again, which really could end up falling flat. I really hope they do a good job of explaining everything, because so far it seems... lame, to be honest with you. 

Great, thanks for the details! I am not a big FPS guy, but Bioshock ranks as one of my favorite games now and I am stoked about Bioshock 2. At first I was skeptical and would've rather they left the series alone since it was so self-contained, but it seems like 2K is really trying to flesh out the story of Bioshock in a coherent manner. Can't wait for E3!

I'm still skeptic on this game, because the original gameplay footage we saw looked very like the first Bioshock. Being able to turn on the Little Sisters (this time as Big Daddy, though), could potentially be interesting. I wonder if your drill will play a part in harvesting the Little Sisters? I think combinding plasmids as the opportunity to make the game easier, with certain combonations, of course. Aside from that, I just don't really know how this is going to turn out, and I hope it doesn't suck.

I'm quite hyped for this game, looking forward to it and finding out more about Rapture, it was a great game! :)

I'm very excited about this game.  Really haven't played the first Bioshock since I beat it, which was around the time when the game first came out.

I'll likely still buy it and play through, but I'm not exactly excited about the whole "ok, now let's make it a trilogy" thing. It didn't bode well for the Pirates of the Caribbean movies, and I think it will be worse for Bioshock.

"

Not sure how I feel about playing a Big Daddy that uses plasmids. That feels more like a gimmick than it does something that needed to be added into the game.

I agree that the moral choices in the original were shallow, but now they lack anything remotely resembling substance. There seems to be really no cost/benefit this time around. How do you think the range of outcomes will be exapnded?

We discussed this Big Daddy thing in the IRC, and if you observe the original, the Bag Daddies don't need to be controlled, and they're already quite powerful as is. They can take on a whole gang of splicers, and no matter what, they do their brainwashed duty. In this game, you're apparently doing the same thing. 

Once again, I compare it to the Pirates trilogy. They took that pretty serious too.

Yea like hamzburger said this game looks gimmicky

Looks nicer than I imagined for a Bioshock sequel, but no PC version?

Sounds like a good chunk of storytelling.  I don't understand why so many people have so much hesitation about this game.  It's Bioshock fucking 2!!!  The first was AMAZING!  How could anyone expect anything less from Bioshock 2?  They obviously saw that Bioshock wasn't broke...so they don't need to fix anything.  All they are doing is adding to the world that we were given, as well as offering another perspective.

I think they will do one. Gamespot seem to have a space for the pc version too. It seems like a no brainer if they're creating the xbox 360 version, as to my understanding its relatively easy to port over.I'm not sure if it would be released simultaneously as the console verisons, but it'll no doubt look a bit nicer too."

BioShock 2 is coming out on the PC, PS3 and 360. As far as I am aware.

The one thing I am really looking forward to in this game is to see how they fix the general combat and gameplay aside from allowing you to use Plasmids in combination with each other and different weapons at the same time. BioShock's biggest failing was it really became a very 'rinse and repeat' style of gameplay from early on which in combination with the more linear aspect of the game was a little disheartening when everything else about it was absolutely superb.

System Shock 2 underwater as a Big Daddy, yawn.

Can I just say...THAT MUSIC IS FUCKING EPIC?!?!?!  My God, I wanna play this game so bad now!!!

Looks like it is going to be good. The inclusion of "choice-driven" NPC's has me a bit skeptical, but they handled the Little Sister choices well in the first, so this will probably just be an extension of that. I am very excited for this....I am trying to ignore the negative chatter.

Hogarth De Le Plante?

What a name

Okay, I'm no longer worried about the game. It looks quite good.

I wonder how they'll balance out the power issues. The Big Daddy's of the first game were absolute powerhouses, flattening anything in their path. What sort of enemies will they dream up can take on such a thing. Plus, the character can use plasmids, another notch of power....

NO! All lies. This game does not exist!
