I found this product to be a bust. After years of all the doom games we were very excited to finally get the new doom. The game is so top end on graphics that only specialty hardware can really run it. This is nothing more than a slide show on both of my new computers. Finally I found one computer that could run it and found it not to be the shoot-em-up game of the first dooms but more of an adventure game. You have to get into this one and really figure out all the clues. It's not a get on and blast away kind of game.
