What is this video game?

My friend is trying to remember a video game he used to play a few years ago. He can remember the character is a small devil guy with a trident and apparently he can produce and ignite gunpowder with it. It's a 3rd person game so you can only see this guy's back. He also remembers one part of a level, where he's in a hall with some shadows and he has to pass through this place which is full of black creatures trying to eat him. And the game isn't very colourful. I know it's not a lot of details, but I hope someone knows what I'm talking about. Thanks in advance!
