This area of the Anomalous Materials, likely connected to the Black Mesa Transit System as well, is located below the Development section of the Anomalous Materials Lab. Sealed with a blast door, two retinal scanners must be operated to open it.


Test Lab C-33/a houses the Anti-Mass Spectrometer and is reached from the Test Lab Access elevator after several corridors. The Test Lab Access consists of a smaller elevator giving access to a third lower level, where Test Lab C-33/a is located. After the Resonance Cascade, the red and the middle one are broken, and Headcrabs teleport in the middle and third ones. In this room can be found three devices containing Plasma Cells, one of them glowing red. The upper Anti-Mass Spectrometer Control Room controls the actions made inside Test Lab C-33/a and has a direct view into it. After the Resonance Cascade, one of them is broken and a Headcrab teleports. In this room can be found two Ionization Chambers. That section, located on the lower level and accessed from the first level through an elevator, features a covered laser running along a corridor, and other features such as the Anti-Mass Spectrometer. On the same level can also be found lockers (including Freeman's), HEV Suit consoles, restrooms, a cafeteria where a meal can be destroyed in a microwave oven, and a guarded access to Sector B. Furthermore, the light in one of the labs can be turned off it will always be turned on again by one of the scientists present there. There the G-Man is seen discussing with a scientist in one of them. The first level also features several small labs. Īs seen in the Security Shift Schedule given to Barney Calhoun, himself and another security guard started their Blue (from 09:00 to 22:00) and Indigo (from 21:00 to 10:00) Shift there on May 15, 200. There he learns that a system crash has occurred earlier at around 08:30. On the day of the Black Mesa Incident, Gordon Freeman enters Sector C from there, in the Half-Life chapter Anomalous Materials. The first level features a lobby connected to Sector C Line of the Black Mesa Transit System, with hung on the wall a world map and the words "Black Mesa Research Facility" above, a security guard welcome desk, a map of the Sector, and a computer terminal sometimes used by scientists to receive data. As you are wandering, check for grates and ducts - remember you have a crowbar and crowbars are meant to be used." - The Portal Device description In fact, there seems to be a number of folks kept a specimens for observation and study, floating around. Run around a little and you will discover that you are not the first to pass through the portal. You have no weapons, save a crowbar, which, if you are smart you will use to pry stuff open. " You have been popped through the portal device and landed feet first in the portal control room. There Colette Green and Gina Cross come with Richard Keller to reset the dampening fields during the Decay chapter Resonance. Storage Area 3 can be seen from the other side of the track.

The area has a view to the Black Mesa Transit System, but it cannot be accessed from there. The lobby contains a security guard welcome desk, as well as an American flag and the same world map seen in Test Labs and Control Facilities. The area is accessed from a lobby with a glass roof where the sky, a ramp culminating to the top and Apaches passing by can be seen, and is apparently connected to the rest of Sector C by an elevator. Partially on the surface, this unnamed area is located above the Development section of the Anomalous Materials Lab, and contains the room located above the Anti-Mass Spectrometer, containing its dampening fields, as well as numerous labs and offices and the dampening locks used to control the dampening fields. 1.5 Area 3 Medium Security Facilities and High-Energy Particle LabsĪpart from separate sections located along the Sector C Line, the main area of Sector C spreads on three main levels, each giving access to a part of the Anti-Mass Spectrometer.1.3 Anomalous Materials Operation Center.1.2.3 Anomalous Materials Lab - Development.1.2.1 Anomalous Materials Lab - Research.
