Half-Life: Resonance Cascade is a full conversion modification for SCP: Containment Breach based on Half-Life game series. This mod serves as a depiction of the Black Mesa Incident from a seperate, farther off perspective.
Lambda Land takes place in the Lambda Facility where you play as Gordon Freeman. In this world, Freeman instead has to turn on the core of the facility and clear the facility out.
Half-Life: The Core is a classic retelling of the events surrounding the Resonance Cascade disaster from a new perspective. Featuring intense action, complex puzzles and believable narrative, through all-new locations within the Black Mesa Research Facility.
