- The reporters at BMRF are responsible for public relations and handle the press - among other things, posting some material on the Internet (with the approval of the administration), collaborating with other news agencies (if possible) and even their own mass media, such as radio and television (not only internally, but also in the Rio Grande or Socorro County). Those are same who publishing newspapers The Mesa Times. Also, it is the BMRF's own reporters who have exclusive access to some areas of the complex, but not always, and at high-level facilities, it is still limited. And during the incident, despite their status, they are also killed in order to "prevent information leaks".

- EOD in BMRF are also present under FRTOU, but in small amount and wearing green HEV suit. Acting as deminers, they are called by Fire and Rescue or overall Incident Command when found dangerous explosives since they aren't capable and can't handle enough with them. HEV FRTOU guards are toughly armored (bulletproof), like other HEV BMSD guards. But unfortunately of reason for game engine features and despite "EOD" status, they're still capable to be killed from explosion. These due to lacking the placement, appear only in Hazard Course response team along with default FRTOU security guards to reinforce them. This also means that (at least in some cases, eg. mine danger) now FRTOU prevails over SSF, so, from now on, to First Response Tactical Operations Unit personnel can be taken straightaway from Special Security Force agents (how the heck bodyguards could demine if they had/have higher clearance than operatives?). They even can be rehired as a rotation, if SSF picked some FRTOU staff before.

- Yellow cleansuit workers are ones from waste disposal division, literally cleansuit custodians. These workers perform damage control, disinfection and professional decontamination in a complex in case of leaks. They are also hired by Fire & Rescue and/or FRTOU to help out in hazardous incidents. Exactly these mentioned in Intercom aka Announcement System as a Damage Control Team.

- In Xen, using exclusive "misc_dead_hev" entries in character manifest, there are being capabilities to make HEV Survey Team corpses more varied, also adding females. Those are only ones who wear HEV helmets with yellow visors.

- Gordon Freeman's head is strictly from HL2 (however texture upscaled), like Breen, Calhoun, Kleiner and Vance; and because of that it WILL NOT be replaced nor from Half-Life: Alyx, nor from Black Mesa: Source, nor from Black Mesa: Blue Shift (despite my beloved maintenance worker's clothing).
