When rebels started to trouble the Black Dawn Legion (reigning bad guys in DPA), they decided to tighten their already strangling grip on the citizens with even more war machines. The 'Arsenal' was just that: a walking weapons platform all wrapped up in a nice 10 foot tall package. Armed with 3 cannons, a minigun and 34 rocket launcher ports (yes, I counted them) the robot was a frightening sight in combat. Its primary drawback was its very sluggish reflexes and speed, causing it to eventually be replaced by another model for specialized combat. The units now serve primarily as front-line support.
