Only one demo version of Blood Omen is known to have been released, and it is for the PC. It consists of the portion of the game from when Kain awakes in his Mausoleum up until he arrives at the Pillars. None of the prologue is present.
The demo can be downloaded from this page. Please be aware that it does not appear to differ in any way from the same section of the full game.
