What is certain is that loads of authors have picked up on the whole vampire thing and churned out vampire books by the dozen. In fact, if you compare the heroes, or anti-heroes of these books, you start to notice that quite a few have a certain things in common. Specifically, they have unusual or vaguely exotic names - you won't find a single 'Vampire Bob' in the pages of these books. Secondly, they have a tendency to be quite pretentious indeed. And finally, they spend most of their time whinging on and on and on about how depressing immortality is and generally moaning about their extended existence.
Some people are never satisfied.
But while the publishing industry has been aflow with vampire books, the software industry has been relatively quiet on the bloodsucking front - until now. He becomes a vampire after being ambushed and subsequently murdered by a gang of brigands, and awakes in the underworld - where he is made an offer he can't refuse by a necromancer, who gives him the chance to return to life and seek vengeance upon his murderers. He doesn't mention that this entails becoming a vampire, and Kain doesn't ask too many questions. And so, playing as Kain, it's up to you to track down his murderers and empty their veins - or slice them up into little pieces, whichever you prefer. Oh, and remember, try not to get caught out in the daylight too much - it may not be fatal, but it doesn't do much for Kain's strength either.
