The attempt failed and it was deduced that a powerful being was deliberately holding the rift open. The experiment triggered a rare quantum event known as a Resonance Cascade, which ruptured the space-time continuum and allowed extradimensional beings from a realm known as the Borderworld to teleport into the facility.īlack Mesa personnel who had survived the initial incident attempted a resonance reversal using an orbiting satellite to seal the tear.
The Black Mesa Incident, also referred to as the Lambda Incident, was a catastrophic event resulting from an experiment carried out by the Anomalous Materials department at the Black Mesa Research Facility.
