Zombies, referred to as the Undead, are a Survival-exclusive pedestrian type appearing in Grand Theft Auto Online. They first appeared as part of the Bottom Dollar Bounties update and returned with the Cayo Perico Survival Week. While Grand Theft Auto has never involved zombies in any official capacity until GTA Online, fan-made zombie mods existed for older GTA games.

3D Universe

In Grand Theft Auto, zombies were first referenced in Grand Theft Auto: Vice City and Grand Theft Auto: Vice City Stories.

The latter, in particular, saw InterGlobal Studios actors wearing zombie makeup featured in the mission Brawn of the Dead. Victor Vance acted as a stunt performer in a zombie movie being recorded at the North Point Mall during this sequence.
