This is set in the same Nosgoth universe as the recent PS2 game Soul Reaver 2. But where that game followed the adventures of good vampire Raziel, Blood Omen 2 (it should really have been called Kill Innocent People To Stay Alive) is the flipside, where you play Raziel's nemesis Kain. Not only has your vampire the ability to suck blood (no, really?), he also has several other powers, notably super-human strength and an ability to shroud himself in mist, always handy for avoiding enemies.
Cleverly, the inhabitants of Nosgoth will react differently according to how you treat them. For example, if you run around slaying peasants willy-nilly they'll eventually cotton on and run away screaming when they see you. Blood Omen 2 is not for the faint of heart, but if you can stomach the claret, you shouldn't pass this by. (HM)
