Hellboy is originally a comic book character created by Mike Mignola, these Hellboy comics are published by Dark Horse. (yes, you should buy them, Hellboy is one the best comic series I know).
However, I must warn you - this game might not live up to your expectations:
- the game engine can be quite buggy.
- some of the fights can be frustrating.
(I ran into many problems with my nvidia TNT2, using their detonator drivers. Installing the drivers from my video card manufacturer (ELSA) seems to have made the game a lot more stable).
So, unless you are a devoted Mike Mignola fan, this game might not be worth your trouble.
