SCP: Secret Laboratory is a multiplayer horror game based on the SCP Foundation universe, where players escape, hunt or survive inside a containment facility. Tesla gates are one of its memorable hazards, electrified gates in heavy containment corridors that discharge on nearby players. Clips built around luring opponents through them spread through gaming montages and short edits because the setup is easy to understand and the payoff is instant. The Z4 wording in the original upload title appears to be a uploader label rather than an official in game name.
