Out of all the flamethrowers I've tried in many doom mods, this one is definitely the best and also the most scary.
Even though the flamer itself well done, featuring satisfying permeable firepower, nice visual effects and adequate sound effects, the thing that makes this thing so special comes from how the monsters react to it, especially former humans. They have a custom death animation where they will be set ablaze by fire-damage sources which is accompanied by horrific screams of agony as they flail around and fall to the floor as charred corpses.
As I was playing, I came across a corridor that was occupied by roughly 20 units of assorted zombiemen and shotgunners. I had the napalm gun out.
The ensuing inferno, flailing humanoids covered in fire, the combined screams of terror and agony made me feel like I had commited an actual war crime.
The level also had particularly gloomy music playing, which further made the whole moment feel all the more powerful.
That kind of immersion is rare. I just wanted to take a moment to celebrate the amount of polish and detail that went into this mod. Its really good.
Aside from that, I've been generally playing this mod a lot and I think its well balanced. I've found the teleporting renegade marines to be very enjoyable and managable to fight, even with starting equipment only. Its worth noting that the kick attack can instakill or seriously damage these dudes, while the z-gun can effectively stunlock with its infinite ammo rapid primary fire. Theres also the double jump, grapling hook and hover to help escape and dodge around. And this isn't even mentioning how max health and armor values are significantly bigger. I wouldn't change anything about them tbh.
I also find it really amusing to be minding my own business killings demons, then suddenly hearing a teleporting sound followed by a "die motherf****r" or "gotcha b***h" and have these guys try to take me down. There is something really comical about their eagerness and edgy-ness.
This is a seriously cool mod.
