Developers love to sneak things by us, and the best possible way to do so is in trailers. Even in small teasers there can be countless hints towards possible gameplay mechanics, story reveals, and other subtleties. Often, to find them all, you need to go frame by frame, looking everywhere for everything. Its a bit of a pain, so we decided to take that strain off of you. That's the concept behind Frame by Frame.
This Dante's Inferno trailer shows us a lot of gameplay and answers a lot of questions. Especially the question, "Will this be just like Devil May Cry and God of War?" That question is definitely addressed.
