[*]Sergeant_Mark_IV's for his Brutal Doom 0.19 (NOT FINAL!)
[*]Zeratul 67 for his Particle Fire Enhancer Mod
[*]PerKristian's for his SFX mod
[*]NightFright and other posters in this thread: http://forum.zdoom.org/viewtopic.php?f=19&t=32628 for his improved version of PerKristian's Smooth Animations mod
What this mod does is simple: Basic features of the Brutal Doom mod are retained such as the gore; location-specific damage, monsters crawling around without legs, body parts and blood everywhere, etc, but the new weapons are removed and replaced by PerKristian's improved versions of the vanilla weapons. That is to say it's the normal doom weapons, but with much smoother animation. In addition, I have taken some creative liberty and kept/added some features from Zeratul67's Particle Fire Enhancer mod, such as shell-casings flying bullet weapons. Lastly, PerKristian's improved weapon sounds have been added in place of the normal Doom ones.
Keep in mind this is a beta at best; I have not fixed all I wanted to, but by and large this was what I set out to make I started messing with this stuff. I have learned so much how editing for Zdoom works, which leads me to this:
This mod is only compatible with GZDoom due to the PFEH mod utilizing some fancy lighting effects!
Any kind of criticism is welcome, apart from commenting on the giant mess inside the archive. I know there's a lot of obsolete stuff, but bear with me!
