"The biggest embarrassment has been Black Mesa facility, but I think that's finally taken care of itself... Quite so."
The G-Man[src]

The Mark IV Thermonuclear Device, nicknamed "The Package", is a thermonuclear explosive device used by the Black Ops to destroy the Black Mesa Research Facility.

Overview[edit]

The G-Man reactivating the bomb.

The bomb is first mentioned by two Male Assassins in a storage area. Later in the game, in the eleventh chapter of Half-Life: Opposing Force, "The Package", Adrian Shephard discovers two other Male Assassins setting up the bomb in an underground parking lot under the large Ordinance [sic] Storage Facility connected to Sector E Materials Transport. After killing the assassins, he deactivates it. Afterwards, he proceeds to a nearby room with a view of the truck, and witnesses the G-Man reactivating it. He cannot return to the truck, making the destruction of Black Mesa inevitable.

The bomb detonates when Shephard is detained by the G-Man aboard an Osprey at the end of the game. He witnesses a white flash from the horizon that blinds him while the G-Man makes a slight pause in his monologue, marking the destruction of the Black Mesa Research Facility.[1]
