Requiem: Avenging Angel (GOG)

Earth becomes the battlefield for an apocalyptic conflict in this late-1990s first-person shooter, where celestial soldiers and demonic forces wage war among ruined futuristic cities and industrial strongholds. You play Malachi, an angelic warrior sent to stop Hell’s advance before humanity is erased or enslaved. The tone is unapologetically grim, strange, and pulpy, mixing sci-fi weaponry with Old Testament-inspired supernatural punishment. Requiem: Avenging Angel feels like a lost contemporary of Sin, Blood, and early Unreal-era shooters, but its religious fantasy angle gives every encounter a distinctive flavor.

Malachi fights through linear missions packed with Fallen Angels, possessed humans, mutated creatures, and security defenses, relying on conventional guns as well as divine abilities. Firearms handle the immediate problem, while angelic powers let you take control of enemies, ignite blood within a target, unleash insect attacks, heal yourself, or petrify foes in salt. These powers consume spiritual energy, so combat asks you to decide when a spectacular miracle is worth more than simply conserving ammunition. Levels emphasize key hunting, switches, enemy ambushes, and occasional environmental puzzles, following the fast, maze-like structure common to the period rather than modern cinematic pacing. Difficulty can be punishing thanks to aggressive enemy groups and old-school save management, but the escalating arsenal and expanding power set keep the campaign moving.

Its best idea is the way sacred magic changes the usual shooter toolkit: possession can turn hostile units into temporary assets, while other powers offer crowd control that ordinary weapons cannot match. The dated visuals, stiff animations, and sometimes confusing layouts show the game’s age, yet its atmospheric soundscape and imaginative enemy designs preserve a memorable occult-tech mood. Players who enjoy classic FPS campaigns with unusual mechanics, especially fans of Hexen, Dark Forces, or Blood, find far more personality here than the premise initially suggests. Newcomers should expect vintage friction, but veterans looking for an eccentric relic of 1990s PC action have a compelling cult favorite to excavate.
