Put it at the first zombie reveal in a gaming montage, after an alert cue and before the action peaks. Pair it with Enemy Spotted to flag the threat, then follow with FNAF Jumpscare Scream when the scare lands for a sharper payoff.
About this sound
This 1.8-second clip is a short Team Fortress 2 Demoman voice line about zombies, with a censor beep covering the swear word. It feels funny and brash, like a loud warning shouted in the middle of a fight. The line comes from the Demoman character in the game.
