ZDoom

Absolutely a good feature.

this sure is a thread

but some of the decorations turn into a front-facing only version of the Nightmare Cyberdemon that cannot be killed and constantly shoots rockets at you. i'm totally stuck as to why it turns into this thing specifically, and i can't find the correct console command to kill it with. it probably won ...

That would be pretty cool.
It would also be incredibly unfeasible, if not outright impossible.

That framerate death is almost certainly due to the presence of one or more Nightmare Elementals on the map. They passively emit Lost Souls (and occasionally Nightmare Souls) when they're active but can't see you, such as when they're waiting in a teleporter closet. Lost Souls in DRLA don't actually ...

you can't consume plasma pistols for ammo because they're assemblies. assembled weapons can't be converted to ammo.

Nope.
But I can't say that I blame you for doing so. They're very mean.

the HPNBFG doesn't really need anything special once you get it working; the fact that you have a High Power Nuclear BFG 9000 is pretty sweet in itself.
if you really want it to go faster, wear some Nuclear (Power)Armor

so stop holding the reload button when you want to switch away from your dual uzis

idk how to give any kind of "hint" for this without being either uselessly vague or basically giving it away
so i'm just gonna go ahead and say it (in spoiler tags, though)

Spoiler: energysaw recipe

PPPA

You also need the Anti-Materiel Rifle (made from battle rifle) and the Energysaw (made from chainsaw; it's been split off from Plasma Infusion and has its own recipe now)

Which assemblies do you already have?

It just looks for the presence of a certain actor native to hdoom, and runs a script if it's found. I believe the brutal detection stuff works in a similar fashion.
The only thing that "c-doom.pk3" does is add a dummy actor with the name of the one being looked for.

Ahoy there! Haven't been around in a while.
Don't mean to sound impatient, but what's the current roadblock in regards to The Update *lightning strikes, horse whinnies* still not being a thing?

I think IHKs are fine if they're avoidable. The Cyberdemon is pretty much a 1-hit killer, but the rockets are easily avoidable. So long as the attacks are fair, I say it's fine. Plus, having wielded a rocket launcher ourselves (and possibly blown ourselves up with splash damage) by the time we ...
