The amount of hype that's surrounded BioShock in the months leading up to its release has been pretty remarkable. Billed as a "spiritual successor" to System Shock 2, Irrational Games' 1999 choose-your-own-adventure shooter, BioShock takes place in the world of Rapture, an underwater city built by Andrew Ryan, an industrialist who was intent on creating a utopia at the bottom of the sea where artists and businessmen could pursue their goals without interference from governments.
Unfortunately, utopias are pretty boring places to stage FPS games, and as such, things went terribly wrong. The citizens were torn apart by crime, and took to rewriting their genetic makeup. This also had the wonderful side-effect of causing most of the civilians in the city to go crazy, so that the failed utopia is now populated by barely-human freaks that want nothing more than to kill interlopers.
Unfortunately for you, your unnamed character has crash-landed on Rapture's surface dock and has no choice but to descend into the city to survive. In order to fight back against the inhabitants, you'll need to adapt their tools for use against them. A large suite of weapons will be available, each of which can use different ammo and be fully upgraded, and you'll also be able to use a large number of plasmids, which are basically spells that can be cast on your opponents for various effects. You can set them on fire, force them to fight for you, freeze them before smashing their bodies, and perform any number of other actions.
GameSpot's Game Guide to BioShock is going to have plenty of tips and tricks for you. In addition to a full walkthrough, we're going to give you suggestions on how to bring down the game's enemies, instruct you on the game's fully modifiable weapons, and round things off with some basic hints. Enjoy!
