I added a set of brightmaps to both versions of the enemy and updated the submission. They're repurposed from those used for the Zombieman (the ones included with gzDoom)--I didn't create them from scratch. I can co-credit whoever created them if that's considered appropriate, but I would need to know who to give credit to.

This seems like a decent enemy. I don't think he's overpowered; I could kill him with
a pistol and no armor easily.

Updated submission with gunfire sound converted to OGG, and added a corpse object for consistency with stock Doom humanoids.
