So... it's got the story of Doom where demons are coming up and being rather demonic about things, the melee qualities of Chivalry or Dead Island (the melee being really the only solidly good thing about that game) and magic abilities that seem to be reminiscent of Skyrim.
Ya know, this may be an alright game if they don't try and bog it down with a bunch of multiplayer modes and other uneeded stuff. Come to think of it, if it actually uses the old doom system where there aren't any objective markers and all is organic and well, it might be a smash.
