The line comes from Blood, a first-person shooter released in 1997, where fanatical cultists serve as recurring enemies and shout ritual phrases during combat. Maranax Infernux is one of those enemy voice lines, preserved by fans of the retro shooter and shared through soundboards long after the game's release. Its survival owes much to nostalgia for 1990s shooters and to horror creators who reuse short, recognisable villain lines to set a threatening tone quickly, without needing any context from the original game.
