The Barney NPC was then used by Valve's AI programmer Steve Bond to run experiments in enemy squad behavior. Originally, all Black Mesa employees were to be hostile to the player.They also say random, sometimes humorous sentences, most of the time when they are idle. This is also the case if a scientist witnesses the player kill other scientists or security guards. If one of them is attacked by the player, they will be afraid and run away from him (regardless if it was intentional or not). Cleansuit scientists do not have this ability. Scientists have some first aid skills and will administer a 25-point medicine boost to a wounded player with a health level under 50. They will stop following the player once they are too far away or if they are attacked while following him. They also tend to be physically weak, dying within a few shots, as well as having no combat capabilities. Colette Green (Level 4 Research Associate)Īlthough cowardly and clumsy at times, scientists can assist the player with certain tasks, such as using retinal scanners to open doors.

Gina Cross (Level 4 Research Associate).Rosenberg (Advanced Physics Researcher).Gordon Freeman (Level 3 Research Associate).Many Survey Team scientists have died on Xen. Because of the danger, Survey Team members are highly trained in the use of the HEV Suit and a variety of weapons. Their assignment is the most dangerous, as they are tasked with entering the borderworld Xen to collect samples and conduct experiments. Survey Team - Survey Teams were organized soon after the first teleportation labs were constructed in Black Mesa.Instructor - Scientists will often take on additional work training employees and conducting simulations in the Sector A Training Facility, as themselves or their hologram counterparts.Hazardous Environment Supervisor - Supervisors act in a similar role to research associates in that they assist in experiments, but they are primarily concerned with maintaining a safe work environment.Colette Green are notable research associates. They are usually required to conduct the more mundane or less desirable portions of a given experiment. Research Associate - Research Associates work alongside R&D scientists, but with a lower status in the employment hierarchy.Most R&D scientists have a limited knowledge of first aid, and can heal some wounds.

The research conducted ranges in focus from particle physics to biological study to space travel.

Research and Development - The largest portion of the scientists are assigned to research and development positions, where they conduct experiments and create new technologies.When you are injured, they will inject healing agents, making them extremely important to your existence. They are your coworkers, mentors, and allies although occasionally they are too busy to even notice you. In the Half-Life Audio Script, the scientists are described as follows: The scientists are brisk and businesslike faced with the stress of fantastically improbable situations, they either devolve into hysterical panic and shock, or shield themselves with hyperrational analysis. Some scientists are trained in the use of the MP5 submachine gun as part of Hazard Course training, but most have little or no combat skills or experience. In Opposing Force, a cleansuit-wearing variation of the normal scientist appears in limited areas. Like other employees, scientists have an assigned uniform, consisting of a blue shirt, white lab coat, red striped tie and white (or beige) slacks. Each scientist is granted a different security clearance specific to his or her duty, with an average clearance of Level 5.
