The company itself was involved with China before the war, and spent a lot of time and resources developing a new incendiary sidearm for them known as "Project Zhu-Rong". Rumors arose and subsequently spread of their activities and L.O.B. Enterprises soon came under federal scrutiny, as political tensions rose between the United States and China. As a result, its employees were required to carry low-grade military weapons at all times, and received training in the event of a federal invasion or nuclear exchange.
The Zhu-Rong v418 Chinese pistol was one of their products, and appears to be a variant of Project Zhu-Rong, as is indicated in their research files, and subsequently lies in the area for the player to obtain.
It is divided into three areas: the main area, east wing, and enterprises archives.
In 2077, shortly after Project Zhu-Rong's completion, the building was invaded by U.S. military security forces, comprised mostly of robots. Most of the employees of L.O.B. Enterprises had safely evacuated the building in time, forcing a lock-down of the facility, pending further federal investigation. However, the Great War broke out on October 23, and the U.S. military robots remained inside, keeping the premises secure for over two hundred years since that time.
1) As soon as you enter the East Wing, there is a reception area consisting of an alcove on the right with two desks, a coffee machine, filing cabinets and shelves. There are two terminals, one functioning security operations terminal, and another non-functioning terminal with the Stealth Boy.
2) As you turn the corner and head west, you engage a Mister Gutsy, between 2 piles of desks and filing cabinets, as you go through, you will find a armor case, containing metal armor or Recon armor, and the Stealth Boy
2 pre-War books: Both of them are on the desk by the R&D Operations terminal but have also been seen in various places on the floor. The R&D room is the first accessible door on the left after reaching the top level of the east wing, in the same hallway as the CEO's office.
The R&D operations terminal is a very hard hack. If you hack it, you can read the progress reports on the prototype pistol.
Zhu-Rong v418 Chinese pistol: East wing in the CEO's office in a metal case on a desk (hard lock, the key is in the CEO's desk and also unlocks the very hard door back to the hallway).
Tumblers Today: Next to the computer monitor on the desk in the CEO's office.
Mini nuke: In the CEO's bathroom next to the garbage can, or on top of the lighting fixure over the toilet, and the bin with a leather belt in it.
Chinese Army: Special Ops Training Manual: Beside the employee terminal in the archives. Best way to get here is to head north from the entrance. Keep heading down the hallway until you see a Nuka-Cola machine to the left. Right next to it is a door that will head down to the archives. Once you enter the archives, go around the long cubicle wall, turn left. The book is next to the terminal on the desk. Looking at your local map, it's the east-northeast most room.
Stealth Boy: In the generator area of the archives past the bathrooms. It's on a shelf on the eastern wall.
While L.O.B. Enterprises does not show up on the Pip-Boy "world map", its entrance is marked on the Pip-Boy "local map". Fast traveling to Falls Church East places you right outside the building.
L.O.B. Enterprises has the dubious distinction of having the most vacuum cleaners of any location. There are a total of 15 across its three zones. (There are 5 in the entrance, 7 in the archives and 3 the eastern wing.)
There may be a sentry bot inside L.O.B. Enterprises on one of the upper floors. The higher the player level the more sentry bots, at level 30 (Broken Steel add-on) it comprises mostly of sentry bots with a few robobrains and one or two protectrons.
Another danger point is one of the entrances to the archives wing. The entire room is filled with explosive gases, and a Mister Gutsy patrols the room (sentry bots will patrol this room if the player has Broken Steel installed and is level 20+); its attacks can ignite the gas.
There is a computer named "L.O.B. Enterprises - Sam Johnson's terminal" located in the main area that appears to be without power yet can be selected for some communications regarding sexual harassment against female employees by Mr. Johnson. To find it, go through the right hand doorway on the ground level upon entry, turn right and follow the corridor around and turn through the left doorway and up the collapsed ceiling to the next floor; it's in the southwest corner of that room.
In the east wing section, there is a bathroom with urinals, however on the outside of the bathroom the sign says "Ladies". The men's bathroom next door does not have any urinals. This may be an oversight, or a joke by designers to nod to the jokes pulled by Sam Johnson.
Just to the right of entering the east wing there is a teddy bear sitting on a chair in front of the security operations terminal.
In one terminal it is noted that in case of emergency the building should be evacuated via the archives. Although there is a section in the archives which looks alike the metro levels, there is no visible connection to any metro.
