(Edit: just the clear things up, this isn't suppose to "fix" anything that was "wrong" with the original. It's a homage to the original piece of work)
Anyway I'm glad someone else here gives a shit about doom.
Pops a disk into the drive....
My Little Pony plays...
Twilight Sparkle: And with the Power of Friendship you can do anything!
Doomguy: *Leans in on the monitor* What should I do... It is like everyone is getting killed and I am expected to fight some climatic battle between Good and Evil in which for some reason I will be forced to fight a head on stick!
Twilight: You know what you should do...
Twilight: RIP AND TEAR!
And doom guy rode a Cacodemon into the sunset!
That was just false advertisement right there, there was NO OTHER marines aside from dead ones
You were alone.
I loved this picture so much I came up with my own personal view of the IDEAL DOOM game (not that I don't love the existing ones), if you have any questions let me know, right now I am just going to list the enemies (bear in mind some are old, some are new and many might have differences to the original):
Chainsaw Zombies (D3)
Possessed Marines (D3)
Possessed Commandos (D3)
Lost Souls (D3)
Forgotten Ones (the old version of Lost Souls, flaming skulls with horns instead of flaming heads)
Vulgar (D3 ROE)
Mecha-Demon (the hound like creature in D3 with robotic hind legs)
Pinky Demon (Classic horned demon from Doom)
Cacodemon (has a new look but is similar to the one in D3)
Ticks n Trites (the two types of little spider demon from D3)
Hell Knights (D3)
Hell Barons (D3, they now have a noticeable difference from knights, slightly bigger and have horns on their face
Bruisers (D3 ROE, smaller versions of Cyberdemons in strength)
Arachnatrons (Doom 2, smaller versions of the Spider Mastermind, they now have a slightly new look)
Gargoyles (New aerial unit that are more or less like Imps but can fly, when they die they break apart into stone)
Pain Elemental (new look but same creature from Doom 2)
Succubus (New demon and similar to the Arch-Vile, it summons new demons to the area and can harm you without touching you.)
Shrikes (New aerial unit with scythe arms and cybernetic parts, slightly harder to kill than average air units.)
The Mother Demon
The Icon of Sin
there are a couple of others I could add but...well I'm curious to hear other people's opinions first
