Blood Omen is the first game in the Legacy of Kain series, developed by Silicon Knights and published by Crystal Dynamics in 1996. It follows the vampire Kain as he seeks revenge on those who ended his human life.
In this TAS, lapogne36 abuses Kain's full moon wolf form, a wrong warp, and other glitches to beat the game in record time.
We also have a run of the game's sequel, Legacy of Kain: Soul Reaver.
