The game is set in fictional dystopian city Rapture in alternative history 1968, eight years after the events of BioShock. The protagonist and player-controlled character is a Big Daddy, a being that has had its organs and skin grafted into an atmospheric diving suit. Among the first of its kind, the player-controlled Big Daddy reactivates with no recollection of the past decade's events, and scours the city in a vain attempt to relocate the Little Sister that he was paired with. When it becomes obvious that Rapture's leader Sofia Lamb will become responsible for the city's destruction, the Big Daddy attempts to overthrow Lamb and her army of Big Sisters.
Not sure if anyone else is playing this, I just got it the other yesterday and it is amazing. The first game was brilliant. I loved it, the storyline, the twists, the city itself, all amazing. This game has all that and a bag of chips. As mentioned above, you're playing as a Big Daddy. At first I was apprehensive, but it's pretty badass. You start with the classic Drill hand and can wield an assortment of guns and of course, the Plasmids or "magical powers". The controls feel like you're actually a Big Daddy; not too swift, heavy as hell (each jump shakes the ground when you land) and powerful as FUCK (AND YOU HAVE A DAMN DRILL FOR A HAND).
There are all the classic elements from the first Bioshock, the Splicers, other Big Daddies and their Little Sisters, and this game introduces the Big Sister, which is basically a "ninja-version" of the original Big Daddy. She's pretty badass, I haven't had an encounter with one that hasn't resulted in me dying. Serious shit.
The story is shaping out to be a good one so far. I don't want to give away many spoilers, but there is an awesome opening sequence which dives you into the game. Basically, you're searching for your Little Sister, and you encounter and interact with other Little Sisters in the process. You have to act as their protector as they harvest ADAM and attract the Splicers - who also want the ADAM. Then there are the moral choices associated with the Little Sisters, whether to save them or harvest them for their ADAM. The story is shaping up nicely, I'm only through the second or third level so far, but there appears there will be some twists upcoming. Hold on to your seat.
The game really expands upon the City of Rapture and it's origins. The level I just completed was an amusement park that featured an exhibit on the History of Rapture as well as plenty of exhibits you can interact with and fight through. It's like fighting through a rideable version of the Hall of Presidents at Disney World. Pretty awesome stuff. The game is sopping with "vintage" references to the 50's culture and the steampunk technology of Rapture. It's all very engulfing and really draws you into the game.
Not only are you exploring new sections of the city of Rapture, you explore the outside of it as well. Since you're a Big Daddy, you can walk along the bottom of the ocean, which for me was just as breathtaking as the first time I stepped out of the Vault in Fallout 3. Early in the game, the glass keeping the ocean out breaks on you and you basically have to navigate the outside of the city to get back inside. While walking the ocean floor, there isn't much to do but take it all in. At one point, I set the controller down and just watched the fish (and sharks feeding on the fish). I also took a few extra minutes to marvel at the whale skeleton on the ocean floor. Very, very good attention to detail. Very immersive.
I haven't got to play any multiplayer yet, but it looks to be a lot of fun, with some new takes on classic MP game types. It also looks to add some replay value to the game which regrettably, the first game lacked.
I definitely recommend this game to anyone who played the first and anyone who enjoys an awesome FPS.
My only gripe so far is that in the first game, you could play through the entire game and still travel back to the first level if you wanted. In the new game, each level is a one shot deal, no chance to revisit it. Nothing huge, but a minor gripe.
