Post-Shift is a fan-made Five Nights at Freddy's game known for its Custom Night modes, where players face variants like Nightmare Helpy and Funtime characters in harder challenges. Its scream effects follow the same tradition as the classic FNAF jumpscare scream, using a loud distorted shriek to punish a missed check. Clips and soundboards have kept that style circulating among horror game fans, who reuse the Post-Shift scream for edits, fan nights, and pranks long after finishing the game itself.
