Biography
At the beginning of the incident, Harold met with his close friend Stanley Rosenburg and Rosenburg's assistants Walter Bennett and Simmons. They formulated a plan of escape which would bring them past not only the Xenian wildlife, but the HECU troops as well.

The plan was that they would escape to the prototype teleporter in an old sector of the lab, and then use it to escape to the surface. They would then use a Black Mesa SUV to escape from the facility.

Unfortunately, Harold was separated from his allies in an ambush, and hid in an office. Two HECU troops soon found him, though, and fired on him. Fortunately, security guard Barney Calhoun was on the scene, and defeated both soldiers. Harold thanked Barney for his assistance, but was too wounded to help him. He revealed Rosenburg's plan of escape to Barney, and then expired.

Barney relayed the news of Harold's demise to Rosenburg and his assistants. All three were saddened by his demise, particularly Rosenburg.
