An old U.S. army facility, the abandoned armory was once a massive ammunition dump, full of various bullets, explosives, and more. It also houses a very rare, very powerful plasma shell, which is fired from the damaged artillery cannon at Cheng's fortress, and used to blow a hole in the wall. It is home to an automated defense system, which will destroy any and all "visitors" to the main storage room. Clearing the location will grant 20 caps.
The abandoned armory appears only in Wastelad.
