5. Classic Doom 3
This mod is a remake of the original Doom game, making use of the “advanced” graphical features of Doom 3 while retaining the feel and gameplay of the original. Only the shareware levels are included, however. Classic Doom manages to feel familiar and new at the same time, the way the world feels once you’ve updated your eyeglasses prescription after a few years of putting it off and can suddenly see details more than ten feet away again.
4. Hexen: Edge Of Chaos
Based on the original Hexen game, Edge of Chaos is a hack-and-slash game with a story that ties into the expansion packs and also touches upon the Heretic narrative. All of the original Hexen inventory items are included, and the visual feel of the original was recreated perfectly. Any Hexen fan must play this mod.
3. Perfected Doom 3
Perfected Doom 3 is more then just a tweak mod — it attempts to completely overhaul the entire game with new monsters, rebalanced weapons, rebalanced monster stats, better graphics, new gameplay features such as “Deadly Attacks,” blood and gore tweaks, ragdoll tweaks, map tweaks, and more. Every weapon and enemy looks, acts, and feels better. This mod does increase the overall difficulty of the game, which makes it great for Doom 3 veterans looking for a challenge.
Sikkmod is a general enhancement mod for both Doom 3 and its expansion pack, Resurrection of Evil. Its main purposes are to update Doom 3′s visuals and to allow the user to customize various aspects of the game, while maintaining the core mechanics and aesthetics.
Based on the video, it looks like a variety of new rendering techniques are being used, such as Depth of Field, SSAO, and Bloom. Not visible in the video are the few changes to gameplay mechanics, such as health regeneration.
What’s also great is that this mod is simple to use, which can’t be said for other customization mods.
1. The Dark Mod

Also included is a version of the Doom 3 editor, called Dark Radiant. It comes with a number of Dark Mod related plug-ins like an Objectives or Conversation editor.
