Mod : Heretic Amplified (Evil Space Tomato)
Links : http://www.doomworld.com/idgames/?id=16428
Reason : this mod is really interesting, it has a simple, but good map design, a lot of new objects, decorations, monsters (including a new D'sparil), ambient effects and weapons, some made by the same author

Yeah, I'll go and give a playthrough to this, see if I can't write up a review on it.
