The Zhu-Rong is a unique incendiary pistol created by L.O.B. Enterprises for the People's Republic of China. The v418 was the final version of the project and was slated for mass production. However, a federal investigation of the company led to the discovery of the company's involvement with the Chinese military. The company was then to be shut down, causing the gun to remain the only prototype in existence.
The Zhu-Rong pistol fires slower than a regular Chinese pistol, and does the same four points of base damage per shot, but has an incendiary effect that adds to its exceptionally low damage over the course of 5 seconds. It has the longest range of all incendiary weapons, aside from the heavy incinerator, and enemies killed with this pistol will often explode into dozens of flaming chunks. It does more damage per shot than a 10mm pistol, but its damage-per-second is actually lower than a regular Chinese pistol (without considering reloading times).
The Zhu-Rong pistol can only be found in L.O.B. Enterprises. It is found behind a Very Hard locked door (requires a Lockpick skill of 100) in the CEO's office in the case on his desk in the east wing of the building. The key for the case is inside his desk. It is also possible to reach the case by working your way around the edge of the destroyed top floor until you are on the other side of the locked door.
