That idea – killing stuff in specific ways to get resources that ensure you can keep killing stuff – has been expanded in Doom Eternal. In Doom 2016, you could kill enemies with the chainsaw to make them drop ammo or dispatch them with a glory kill to make them drop health. 'Take what you need from the enemies' was the mantra at my demo. But it's also a smarter, more creative Doom that uses old favorites and new tricks to refine the rip-and-tear formula without sacrificing what makes it so compelling. It's still got secrets to find, guns to hoard, and lots and lots of demons to kill. It's a fast, no-nonsense, old-school first-person shooter, and it builds on the previous game in meaningful and noticeable ways. Doom Eternal is exactly what I wanted from a follow-up to 2016's delightful Doom reboot.
