Hard Doom is a replacement/enhancement mod that replaces all monsters in Doom 2 with versions that are similar in role, but more dangerous. In general, Hard Doom is geared towards players who want a more difficult, genuine survival experience, and it has a variety of visual effects that are more subtle and don't block your view of the action. Over the years since its initial release, it has been meticulously balanced and rebalanced, with new features and effects added to make this a great mod to play through the popular megawads with, without changing Doom's flavor or core gameplay. This mod requires ZDoom, GZDoom, or Zandronum in order to play!

V7 of Hard Doom includes some new effects, three new enemies (two are done right now!), and a bunch of balance changes. Here's the current change-list and previews of the two new icy enemies!


125 Health

Ancient Apparition
500 Health

Current Change-list:

  1. Added glow to nukage, lava, and teleport flats.
  2. Added lens flares to decorations.
  3. Added lens flares to powerup orbs.
  4. Added the line powerup effect to armors.
  5. Adjusted the homing projectile speed and aggressiveness on the Hells Fury.
  6. Removed +MissileMore from the Hells Fury.
  7. Lowered the height of the Hells Fury skull projectile. This should cause it to explode on low ceilings less.
  8. Rictus Kamikaze explosion damage reduced to 32 (from 64), total damage on direct hit is now 42-112.
  9. The Rictus will now kamikaze at 20 or less health (down from 25).
  10. Rictus painchance raised to 160 (from 128)
  11. Increased the super shotgunners delay after firing by 7tics.
  12. Increased the spread on the Dark Cyber/Spiders BFG10k's to "6, 2.2".
  13. Decreased the splash damage of the Archons comet to 64 (from 80), it now does 74-144 damage on direct hit.
  14. Removed +Missilemore from the Crackodemon.
  15. Removed +Missilemore from the Mafibus.
  16. Reduced the explosion damage of the Pyro Demons fire shot by 32 and increased damage by 2 (now hits 100-128 down from 130-144).
  17. Reduced the damage of the Pyro Demons "FireBombExplosion" by 32. This will reduce the overall damage of the Pyro Blast attack. It will still insta-kill you on direct hit though.
  18. Increased the spawn rate of the Shadow Demon, Hellfire Revenant, and Hells Fury to 8% (from 5%) to give better variation of enemies.
  19. Added a rare Lost Soul replacement known as the "Visage". It spawns with an 8% chance.
  20. Added a rare Pain Elemental replacement known as the "Ancient Apparition". It spawns with an 8% chance.

You are still working on this? I've heard of this mainly because of word of mouth when talking about gameplay modifications and I'd have to say its better than vanilla doom for a challenge even on wads that have more than the usual amount of monsters! It would be nice for occasional new images atleast to show you haven't forgotten about us fans :)

Yeah but I haven't made any progress since the new enemies and re-adding footstep sounds. I'm still waiting on sprites to code the new arachnotron. I will also be dropping support for Zandronum with the v7 release, as nobody really plays it online anymore and there is some stuff from newer ZDoom revisions that I want to use to make the experience a little better.

Any news on the release of v7? I'm having the old Doom itch and this would be a perfect incentive to start yet another playthrough.

I honestly have no clue at this point. The person that was doing the sprite set for me never finished it and gave up. I found someone else to do it but they have no motivation lately.

That's too bad. :-(
Still, thanks for all your work on this; Hard Doom is probably the most enjoyable monster/weapon overhaul I've played in 20 years of Doom. I'll make sure to check on this site every now and then, in case the situation changes.

Just wanted to say that I greatly enjoy your work! I've played Doom and Doom II so many times that I know by heart where everything is and which enemy will spawn where, so this mod is exactly what was needed to make me load up the good old .wads again. Can't wait for another go when v7 is out.

probably my favourite of all the gameplay enhancements, if only because focusing on enemy variation and difficulty is to me probably the most important part of making Doom challenging to veteran doomers. Eventhough I haven't been at it for long, I've played many shooters before so this is my meal ticket.

Glad you enjoy it! The next version is going to include a rare Lost Soul, Pain Elemental, and Arachnotron. This way finally all enemies will have a rare spawn variant. I'm also including some minor visual effects like lens flares which add to the mod but won't greatly decrease performance or distract you/block your view.

Love the mod, i always searched for a mod that would surpass the original in difficulty. i would play coop on vanilla just to try and survive with one life! it's crazy lol until i finally found hard doom on zandorum! Also, is it possible to add many more monsters from realm 667? i have some in mind, Heaven Guard, Jetpack zombie,BFG commando, slime imp, time imp, weakener, volacubi, zomie railgunner, lava demon, there's just so many cool variants of lost souls and other doom monsters!
