Bethesda capped off its QuakeCon 2018 keynote address by showing off the first gameplay video for Doom Eternal, the sequel to the 2016 reboot. The follow-up was originally announced during the publisher's E3 2018 press conference with an exciting cinematic trailer, which was shown once again during the QuakeCon keynote, before game director Marty Stratton and creative director Hugo Martin appeared on stage to discuss the sequel.

Once again, Doom Eternal will be about killing monsters with badass guns, and for the sequel the Doom Slayer will be the "strongest, most badass hero" id Software has ever created. The Slayer has had a makeover and has a new weapon called the Ballista, which can spear demons with an explosive bolt.
