Monsters: Cacodemons

Monsters: Cacodemons

Let's adapt the cacodemons from the various Doom games to GURPS (in mechanical terms) and D&D (in flavor terms).

Ultra-Tech: UAC BFG-9000

Ultra-Tech: UAC BFG-9000

Let's stat up the other energy weapon from Doom with the Beam and Blaster Design System article and TheRyujinLP's houserules. It's not going to be 100% authentic, but representing all the tracer beams stuff is a big hassle - let's settle on a single-shot weapon that needs 3 seconds of charging to fire an explosive projectile that contains TL9 C-cell worth of energy.

Ultra-Tech: UAC Plasma Rifle

Ultra-Tech: UAC Plasma Rifle

Remember Pyramid #3-37? The one with the Blaster and Laser Design System article? I do. If you do, I suggest you to check out GURB and Hard Maths, as they have a ton of additional options for that article. Let's play around with the beam weapon design system and try to recreate the plasma rifle from Doom.

Monsters: Imps

Monsters: Imps

Here we have several impish monsters. The D&D version of imp is a small shapeshifting devil with a poisonous sting. It's weak, but can be very annoying thanks to the invisibility. The imp from the classical installments of Doom is a weak monster that can scratch and throw fireballs. The nightmare imp from Doom 64 is the classical Doom imp on steroids and with chameleon skin. The imp from the modern installments of Doom can cling to walls and ceilings and jump very far.

Monster: Arch-Vile

Monster: Arch-Vile

"One of the worst of a bad lot. You can't think of enough rotten things to say about him. He's fast, hard to kill, casts spells, and resurrects dead monsters! At least these suckers are rare."

― Doom II Manual description

I couldn't have said it any better. I hate these guys, and always will. They are primary targets, but they are hard to hit if they are surrounded by other monsters. They do not have any problems hitting you back though. And if you clear out the monsters in the way, the arch-viles just resurrect them back.

Here's my GURPS adaptation of this truly vile monster. His supernatural abilities are presented in a form of Sorcery spells, so they may be useful even for those who won't use the monster.

Ultra-Tech: Modern BFG9000

Ultra-Tech: Modern BFG9000

We all know and love the classic BFG9000, but its modern (Doom 3 and 4) variant is easier to use, has less unique mechanics, looks less cool, but is deadly as ever. Let's take a look!

Ultra-Tech: BFG9000

Ultra-Tech: BFG9000

Sometimes you need a big gun. And do you know a gun bigger than BFG9000 from Doom? Here's my attempt to convert it to GURPS and this is probably the case where you shouldn't convert the exact mechanist and just stat it up as a cone attack, but I decided to try to make it closer to the original source. Some numbers probably should be tweaked, mechanics simplified, but it still works, although clunky, right?
