The '''Advanced Biological Research Lab''' is Black Mesa Research Facility area located near Sector G's Hydro-Electric Dam and partially above the Biological Waste Processing Plant. Controlled by the HECU, it covers the ''Half-Life'' chapter ''Questionable Ethics''.

The Advanced Biological Research Lab ground floor features a large lobby that gives access, through a revolving door, to a road passing by the Hydro-Electric Dam and leading to freight hangars (this is the road partly taken by Gordon Freeman during his journey to the Lambda Complex). As seen by Adrian Shephard later in the Black Mesa Incident, the road is obstructed by Spore Launcher|Race X moss, blocking the access to the dam. It can be reached from the Biological Waste Processing Plant through a drain located in a small room where Houndeyes are being kept in captivity. There Freeman mostly has to find a scientist to operate the retinal scanner located in the main lobby, allowing him to continue his journey.

Spread on two levels, the ground floor features two Sterilization Chambers, rooms that WikipediaGib (video gaming)|disintegrate any biological form they contain with their Biological Sterilization System using electrical current, primarily used in case of alien containment system failure (they can be used either to kill Standard Headcrab|Headcrabs or HECU soldiers easily, as they seal themselves from the outside when operated). The ground floor also features a surgical unit that can apparently perform surgical operations on two beds at a time, several Alien Grunts kept alive in large tanks, and Headcrabs contained in glass cases. Near the surgical unit, Freeman finds three scientists hiding from the grunts, and one of them explains that their colleague Peters turned it on, but was likely killed by it. Freeman has then to turn it off so that a scientist can follow him to the main lobby. 

The second floor is dedicated to testing a large high-powered laser. There HECU soldiers are fighting Bullsquids and Houndeyes. The Tau Cannon is also found in one room, after a security guard overcharges it and kills himself and a nearby scientist (it was possibly developed there, although one moden is also stored in Lambda Complex).

==Behind the scenes==
*The name of that area is given in one of the numerous Black Mesa Announcement System announcements not heard in-game, and found in the file "sentences.txt" located in the ''Half-Life'' sound folder. There the name is found near the map name prefix "C2A4", which concerns its maps and that of the Biological Waste Processing Plant, whose name is also given there.

*On the main lobby floor can be seen a logo featuring the Latin words "Superbus Via Inscientiæ", and a WikipediaDNA|DNA WikipediaDouble helix|double helix in the middle, designed by Karen Laur.http// ''Half-Life'' section on Karen Laur's official website (textures) The best translation for that sentence would be "Proud by way of ignorance", although the phrasing is not common.

*In ''Half-Life'', only blood stains and gibs remain of Peters' corpse in the surgical unit. In ''Half-Life Source'', his body was added as a retcon.
