DOOM Reviews: 10 Early Reactions You Need To Know

8. You Regain Health By Pulling Off 'Glory Kills'

"A Glory Kill system which doles out bonus health when a sufficiently wounded enemy is melee'd creates a pounding sense of flow: dodge, shoot, dodge, shoot, thump, repeat. This is a game with a beat. It feels good. Speed is everything, but it doesnt feel frenzied so much as it does rhythmic." - Rock, Paper, Shotgun

As a way to ensure you never have to worry about not being equipped for the next fight, health boosts are tied to pulling off 'Glory Kills' - fatality-esque total eviscerations of your opponents.

The nearest comparison I can think of is THQ's underrated The Punisher, which also gave you HP if you pulled off a fancy interrogation, yet in DOOM, it's entirely in service of ensuring you never have to lay off attacking for a second.
