Quake was released in 1996 by id Software and became a landmark for 3D first person shooters, with zombies as one of its early undead enemies. Their pain sounds were part of the game's gritty sound design, built to make combat feel brutal in dark medieval levels. Clips like this one later circulated on soundboards and in fan edits, separate from the full game. It remains popular with retro gaming creators who use the groan as shorthand for old school horror and undead damage.
