I've been trying to decide what other weird weapons I want to add to my pack along with the pipebombs I've showed off before, and I've got a few stewing in some early notes documents here and there, but I was quickly inspired to make this behemoth, the Black Hole Generator, or BHG. Most of the base weapon code pulls from the standard BFG-9000 that HDest defines, but instead of a giant ball of Gretchenfrage flavored death, this gun fires, as the name implies, a Black Hole Singularity.
Still working on the graphical assets while I nail down the mechanics, but I finally got this thing behaving in a way that doesn't immediately crash or destroy itself out of nowhere, so that's progress!
