You might want to give it a miss entirely. It's apparently not made by the same company that did the original, and it's pretty crap as a result. I've only played 1 level so far, but hearing the half demon/half angel guy you're supposed to be playing saying "I love the smell of evil souls in the morning!" or "Yummy, tastes like chicken" after every 5th kill gets annoying in a hurry. Doesn't look like the weapons or enemies are up to the same standard either.
