System Shock 2 - Subsite @ GameBanshee

GameBanshee writes they have set up a subsite for System Shock 2, including a walkthrough and database:

Within this small section of the Internet, we've prepared an annotated walkthrough, a character creation guide, tech skills, weapon skills, psi powers, O/S upgrades, audio log summaries, enemy profiles, an extensive equipment section, and a whole lot of other content for you to pore over when you find yourself returning to the classic.  And if you haven't yet scheduled a replay, you should.
