The '''Topside Motorpool''' is a Black Mesa Research Facility area located on the surface of the compound. It is visited by Gordon Freeman during the ''Half-Life'' chapter ''Surface Tension''.
==Overview==

This area features the bulk of Black Mesa's still-functional military facilities, as well as maintenance and storage areas for the Black Mesa SUVs. Connected by a sewer system to a Black Mesa desert|large cliff and located not far from the Topside Hydro Plant, it includes, among others, an Ordinance Storage Facility surrounded by two HECU Snipers and Land Mines, and containing two rockets topped by nuclear warheads and trapped by Laser Trip Mine (Half-Life)|Laser Trip Mines, a barracks building including the Topside Armory (containing Fragmentation Grenade (Half-Life)|grenades, SPAS-12s, Submachine Gun (Half-Life)|Submachine Guns, 9mm Pistol (Half-Life)|9mm Pistols, Rocket-Propelled Grenade Launcher (Half-Life)|RPGs and their ammo, Tau Cannon / Gluon Gun ammo, .357 Magnum|.357 ammo, Laser Trip Mines, and finally Satchel Charges), a double helipad where an Osprey Heliplane|Osprey continually unloads HECU troops, at least three helicopter hangars (Hangar 16, seen in-game, and Hangar 1 and Hangar 4, only mentioned by the Black Mesa Announcement System), a garage with three Black Mesa SUVs, a small indoor parking lot where a Gargantua fights HECU soldiers and destroys Black Mesa SUVs, and other ruined buildings. The indoor parking lot leads to the Waste Processing Area 3, where the Gargantua is destroyed by Freeman thanks to the Tactical Map installed there.
The area is swarming with Alien Grunts and Vortigaunts, and Freeman is caught in the crossfire between them and the overwhelmed HECU soldiers, who set up an Artillery Cannon and Tripod-Mounted Heavy Machine Gun in the area. There, Freeman also first witnesses the Alien Crafts that unload Alien Grunts in the area, at some point bombarded by a jet, first acquires the Hivehand, and is first confronted by the two HECU armored vehicles, the M1A1 Abrams and the M2A3 Bradley.
==Behind the scenes==
*The name of that area is given in Black Mesa Announcement System Black Mesa Announcement System/Quotes|announcements both heard and not heard in-game.
*One unused scientist sound indicates that a Gargantua was apparently to be fought on the helipads instead of later in the parking lot / Waste Processing Area 3.''Half-Life'' files
*Early ''Half-Life'' screenshots indicate this area was at some point to be visited during nighttime, starting in the previous area, the Black Mesa desert|desert.
==Trivia==
The map where the Topside Armory is located was turned into a ''wcTeamFortressTeam Fortress Classic|Team Fortress Classic'' map, with minimal modifications, named "Hunted".
