Doom Eternal is a high-velocity first-person shooter that pushes aggressive combat, weapon mastery, and arena-style movement to the extreme. As the Doom Slayer, you battle demonic hordes across Earth and beyond using an arsenal of moddable guns, the Crucible blade, shoulder-mounted equipment, and acrobatic mobility that rewards nonstop forward pressure. The game layers resource economy into combat — glory kills for health, flame belch for armor, chainsaw for ammo — creating a deliberate loop of controlled aggression. With a polished campaign, optional Slayer Gates, master levels, invasions, and DLC expansions, Doom Eternal delivers a relentless, skill-demanding combat sandbox.
