“This isn’t Doom 4. This is actually Doom, straight up, from the beginning.”
That’s part of the introduction to an hour-long walkthrough of DOOM‘s singleplayer campaign. The video divides into three main sections, with the player jumping forward to later levels in order to show various features, and the whole thing has commentary. The combination of that commentary and the video itself has eased my concerns after the disappointment of the multiplayer beta. I want to play this. I’ve explained why below, as well as providing handy links so you can jump to interesting points in the video rather than watching the full thing.
