Thank you for the feedback! I did mainly test the mod in Doom 1 rather than a variety of maps, so balance could be a bit skewed. Hopefully I can change that!
I agree that the Revenant sounds aren't great. I couldn't really think of what they'd sound like without just reusing Perk's HD sound effects. I'm glad you like the other sounds!
As for optimization, ouch! I was going to figure out a way to limit shell casings, barrel debries, and other garbage lying on the ground, but kept procrastinating. That save file bloat sounds really bad and I'm sorry for the trouble with it.
Hopefully the new SSG reload being a little faster will help balance it. I do wish I wasn't so limited in the sprites, but there really aren't many angled SSGs I've been able to find. If anyone can point me to some, I'd be forever in your debt.
To cap off this wall of text, I'm surprised about the comparisons to Hideous Destructor! HD is my favorite mod, but I don't think this holds a candle to it in terms of quality, attention to detail, and enemy behavior. Speaking of enemy behavior, I've been considering making it so gun-using enemies may "consider" (random chance) prematurely reloading their guns as long as you can't see them. Both to add new tactics (baiting enemies into reloading to get the drop on them) or just to make them feel more alive. I'm not sure about it, since random chance-based mechanics are very iffy and I'm worried sight checks on a bunch of enemies could cause performance problems. Anyways, when I'm able to tinker later today I'll try to make optimization less of a dumpster fire. Thanks again!
