Zombie Shooter 2 is the 2009 sequel to Zombie Shooter from Sigma Team, a top-down action game about fighting hordes of infected mutants in a quarantined city. Its combat relies on short, harsh enemy cues so players can hear an attack even in crowded fights. Clips like this attack growl were later ripped and shared on soundboards for reuse outside the game. It remains popular alongside other horror game cues such as the FNAF Jumpscare Scream because a single undead snarl instantly signals danger in edits, streams and fan games.
