Bethesda talked about a number of different games today during the QuakeCon 2018 keynote, including The Elder Scrolls Legends, Rage 2, and—naturally—Quake Champions. But Doom Eternal was the big attraction this year, and id Software main guys Hugo Martin and Marty Stratton did not disappoint. 

Doom Eternal will have double the demons of the Doom reboot, and the Doom Slayer will be amped up to handle them, with updated armor that includes a retractable blade (similar to Mass Effect's Omni-Blade, but more imposingly vicious) and what I believe is a portable flamethrower. (And yes, the chainsaw is still at hand too.)
