SCP: Secret Laboratory is a multiplayer horror game by Northwood Studios, first released in 2017 and based on the collaborative SCP Foundation fiction universe. Players take roles as scientists, guards, Class-D personnel, Chaos Insurgency and playable SCPs trapped in a breached facility. Short voice reactions from matches are widely clipped for soundboards because the proximity chat produces panicked, funny moments. This H-humans stammer circulates as a quick reaction for the instant one faction spots human opponents, and it remains popular in SCP edits, Discord calls and gaming memes.
