Half Life Resonance Cascade Further development mod for SCP - Containment Breach

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 separate, farther off perspective. You, Dr. Ben Walker, Clearance Level 4, have been assigned to test on BMR-500, a robot that displays extreme hostility, but is fortunately only able to move while outside direct observation. Midway into the testing session, you hear the alarm and the scientists say they have it under control and it's not much of a problem. Turns out it is, as the electricity shuts down and the robot kills your buddies and the guard. Sector C Personnel have been ordered to evacuate the area until further notice. How far will you go to get to the surface?
