Weaponry B is a level in Keen 2, with no official name. Only the letters "WB" are written next to it in the Vorticon Mothership blueprints. It is probably one of the two weaponry stations in the ship, the other being Weaponry A.
According to the unnofficial name, and the drawing of a gun on the level as seen from the map, this level should be a weapon storage facility of some sort. In fact, this level has the highest number of Vorticon HyperPistols of all the levels in the game. It is a very dangerous level, containing several hazards, fifteen Grunts and three Vorticon Elite. This level, along with Weaponry A, is located in the frontal paws of the Mothership, suggessting they may serve as secondary attack systems of some sort.
The level is structured this way: it is made out of solid steel walls, and it has a big acid pool at the beginning, which can be avoided using moving platforms. Below the pool, there are two separate areas: a smaller, enclosed area to the right, with some ammunition; and a bigger, maze-like area to the left. This second area eventually goes to a huge plasma pool at the bottom of the level. After Keen makes his way over it, he can reach the exit.
This is the only level in the game not to have the distinct grey-patterned wallpaper present in every level. Instead, it has a uniform green-light blue background.
