Blood Omen is a two-dimensional action-adventure game. The player controls the protagonist, Kain, from a top-down perspective. Gameplay is divided between outdoor traversal and dungeon crawls, entailing hack and slash combat, puzzle-solving, and navigating hazards. To advance the story, Kain must locate and defeat the members of the Circle of Nine—who act as boss enemies—and return their tokens to the Pillars of Nosgoth. (wikipedia.org)
