Glory Kills are melee executions used on staggered demons. Each one is unique to the demon type and your position relative to it, front, behind, or on top.
When a demon takes enough damage it staggers, highlighted with an orange glow when close enough. The Slayer can then perform a Glory Kill melee finisher destroys the demon and drops health.
This mechanic is central to Doom Eternal's design: aggression for survival. Players are rewarded for staying in close combat and keeping the "Kill, Gather, Kill" gameplay loop.
