A bizarre affair of a shotgun and sledgehammer, brought by a dimensional breach generated by the [REDACTED] facility's XRM. Closer inspection reveals, on it's head encrusted with dried blood of unknown origin, written in marker is "The Decimator," and "Property of Aila," on the shaft. The face of the hammer possesses 4 one inch long spikes that you reckon would be ineffective against the body armor of the 2030's. The weapon is chain-fed by a small basket of 12 gauge shells, and has a small trigger, that when depressed and the hammer smacked against whatever with sufficient force, fires a point-blank shot, which you assume would be enough to decimate anything that it hits, giving credence to it's name.
Probably going to be used in some sort of Decaying Winter event, or that SQ side-view fight thing I've been planning to work on for a long while. Free to use with credit. (Aila is the name of the Sledge Queen character in the non-canon Archeximus game Demise of Eden, but I think it's her canon name)
