'''''{{PAGENAME}}''''' is the second chapter of ''Half-Life Blue Shift''.

{{See2|story information|the Half-Life Blue Shift storyline article}}

As the chapter begins, Barney Calhoun leaves the Black Mesa Transit System|tram and tries to enter his Area 3 Security Facilities|workplace, but the entrance door fails to open. The Black Mesa Security Force|security guard on the other side informs him that the door is not responding to Barney's pass ID, so he has to wait for the guard to get it open. While he is waiting, Gordon Freeman passes by in another tram.

When the door is open, the guard explains that they've been having problems all over the facility this morning, including system crashes and security malfunctions. After Barney acquires his Armor vest and helmet|uniform and 9mm Pistol (Half-Life)|sidearm, he is sent to help some Black Mesa Science Team|scientists who are having problems with the main access lift in Sector G.

Since the trams are also having problems, Barney walks through maintenance areas to reach his destination. He arrives and activates the elevator. The Black Mesa incident occurs during this ride. Eventually the elevator stops and crashes down to the ground floor.

==Behind the scenes==
David Mertz was responsible for additional level design work on the chapter. The other contributors are unknown. It is possible that Rob Heironimus was one of them. His photo and a reference to him can be found in the map "ba_security2" as Easter eggs. In ''Half-Life Opposing Force|Opposing Force'', the same photo can be found in a level that he worked on. It was most likely placed there by himself.

There were Automatic Turrets placed in various areas of the Area 3 Security Facilities, including the FileInsecurity early24.jpg|entrance and the FileInsecurity early27.jpg|locker room. Although cut, the one in the entrance can be found in the tram ride version of the level, "ba_tram3". When the player harmed any of the characters in these areas, they would turn on and attack the player, right before the game over message.

===Easter eggs===
The locker room contains a couple of Easter eggs. The names of the developers can be found on the lockers. This has been a tradition in the series since the original game. A photo of Rob Heironimus with plastic Easter eggs in his eye sockets can be found in a broken stall. The photo was taken by his co-worker John Faulkenbury in Easter 1998 (see the Easter eggs page for other appearances of the photo).http// John Faulkenbury's comment on The Easter Egg Archive

Barney's locker has two personal photos, two fictional books titled ''Government Conspiracies'' and ''The Truth About Aliens'' by RH, a nod to Rob Heironimus. Gordon Freeman also has a copy of this book FileDy dorms0052.jpg|in his bedroom, as seen in ''Half-Life Decay|Decay''. The last item is a small cardboard box. When destroyed, it reveals a Chumtoad. The player can only break the box by using all the ammunition that is available in the level.

When the camera that shows Gordon Freeman is used six times in the surveillance room, it triggers a scripted sequence where FileDancing scientist1.jpg|one of the scientists dance while the other watches him. In the lobby, there is an FileBa propaganda1.png|advertisement poster with a photo of the shooting range. The very small text on the poster says "Yes, those men are fine examples of natural born man killers. Black Mesa employs nothing but the best!".

===The bridge===
In the cut ''Decay'' mission, Central Transit Hub, the players would use a bridge to crush a Gargantua to destroy it. The FileOther5 cut.jpg|design for this bridge appears to be similar to the FileMaint bridge01.jpg|one found in the maintenance area of the chapter. It is unknown if they recycled the same brushwork.

The player can monitor several interesting key areas from the video surveillance room. These show Gordon Freeman when he is heading to the locker room to get his Hazardous Environment Suit|protective suit, Gina Cross when she is delivering the Materials Handler|crystal sample to the test chamber, and the armory nearby.

The FileOtis donut.jpg|overweight security guard variant from ''Opposing Force'' appears in the shooting range. The The G-Man|G-Man is seen in a tram passing by when Barney is going through a maintenance area. This is his only appearance in the game. The level code for the chapter is "Barney Goes to Work" in the Half-Life (Dreamcast port)|Dreamcast version.
