Do "gore junkies" exist? I mean, seriously.
Also, this video totally did not sell me on the game. Looks like Darksiders with more numerous but less capable enemies. Mass combat was best done in recent memory in Batman: Arkham Asylum, and no God of War clone nor Dynasty Warriors-"inspired" game has anything nearly as sense-making and skill-centric.
Also, why did they talk about cover mechanics with healing? This is not a FPS. This is not a 3PS. Who takes cover in a beat-'em-up? And for that matter, why indicate positively that your game is wade-in-carelessly-and-maul-everyone? That sounds either completely easy or not sufficiently responsive to skillful manipulation to have much in the way of difficulty curves (For what it's worth, this concern has likely been taken care of in development, but the marketing-talk brings rise to the question nonetheless).
Bear in mind, also, that this is coming from someone who could be described charitably as "apathetic" about Warhammer 40k. Setting concept: "Hey guys, you remember when Christianity was awesome?"
