+Good weapon redesigns that fit different situations, as well as sensible keybind organization (though it takes a little bit of getting used to)
+Neato blood aesthetics
+Cacodemons pop like balloons lol
+Not just some chintzy mod that you play a map or two of and go "whatever", it is actually really fun
+Silencer for pistol isn't extremely useful, but when it is useful, it's benefits and obvious and not over-exploitable
+Friendly to users who don't use freelook
+Fun alt-fires
+Awesome titlepic
-Shotgunners do a little too much damage (try playing E3M9 of Doom or MAP09 of Doom II)
-Demons have range that lets them bite through some windows (intentional?)
-Also, demons feel a little too lethal with their combination of high speed and damage output (I know that it's the intention of the mod, but even one or two demons can, in some cases, ruin large sums of your armor and health in a split second) perhaps they could use a little more delay before their bite registers or a slight damage decrease
-Shotgun seems to outclass the SSG in nearly every way (speed, range, damage per second)
It's a really good weapon mod. Makes lots of the enemies a lot scarier and forces you to pay attention to even the smallest aspects of combat. Love it, even though I'm pretty bad at it
