In the visuals, we see an interstellar view of Earth as demonic hexagrams begin to form all around the planet. As the armies of Hell slowly begin to invade, the protagonist, Doom Slayer, approaches the scene. Cutting to in-engine gameplay, we see the game’s tutorial introducing players to staple DOOM mechanics, including the fast-paced shooting and chainsaw-wielding, eventually getting players more familiar with the title’s assortment of sci-fi guns as they begin to disembowel zombies, monsters and other ill-tempered foes.
