Grimm Quest for the Gatherer's Key is a Hack and Slash Fantasy game with some platforming elements that leans heavily on extremely bloody and satisfying gameplay. Players can explore a huge world that often offers several different routes that lead to accomplishment. Almost every part of it is customizable to taste, not only the graphical aspects but also it's gameplay aspects.
I've worked on new gibs and blood effects for the monsters in Grimm. I've opted for extremely bloody and effects that stay around for a long time as well. It makes for a pretty gruesome gameplay experience.
