I just spent ages picking through this thread and its awesome!
Totally don't expect anyone to get this one but here goes.
Its a demo i played once, I'm thinking its about early to mid 2000 so it's not all that old. Its first person and cartoonish 3d graphics. The aim was to walk around shooting little possibly cute animals? I also remember some sort of container you had to fill with blood to level up or something? It was pretty gruesome. I remember parts flying off when you shot the animals.
