Map Packs:Community Bonus Packs 1&2 are two excellent map packs. Gameplay and/or graphics at their best. Not sure if it's included in ECE edition, though. But if it's not, you must get it.
Unreal Community Map Packs are 4 great map packs.
Single Player mods:Damnation: Hell Breaks Loose: It's steampunk time! A great single player campaign with 3rd/1st person view. Highly recommended!
The developers are currently doing a second project using this universe on the UT3 engine... edited by Codemasters.
If somebody is interested...Out of Hell : a survival-horror zombie themed. We can see the huge influence of silent hill on this one, what can I say... it's a demo and can be buggy, but it's damn worth it. Highly recommended!
MetaBall: A puzzle adventure game using a lot of physics. You are a ball and you move through the levels via a hub, earning stars and unlocking others. Great atmosphere... the developers were planing to do a UT3 version but they lacked motivation, and the official website is down. Highly recommended as well.
Some screens are here!
Hollow Moon: A visual and audio experience, states the website... it truly is. Horror at its utmost. Grab it
here.
Ashura: Dark Reign: Currently in tech demo state, this mod plan on giving UT2004 the feel on a sonic game... just try it, it's damn good!
Multiplayer mods:Killing Floor : A scary experience. An awesome experience. Fight against hordes of zombies and weird monsters in co-op... truly outstanding ambiance, very polished and really far away from Left 4 Dead. Recommended, played a lot with friends.
Tactical Ops: Crossfire : A terrorist / counter terrorist mod. Very professional and lots of gamers around... they are already developping a sequel for UT3 and released a stand alone game on the first Unreal Engine. Recommended.
Spawn of Deflebub : An damn original mod where you have to shoot the others at third person view, with different kind of bullets in a little arena where you can build walls. A 8bit feeling makes it quite retro, intentionally. I had a lot of fun playing with friends! Highly recommended!
Deathball : A... sport mod. Really fun, you have a ball in the middle of the map and you have to send it to the adverse goal. No weapons, just the ball grabber/launcher, and only the one carrying the ball can die. Very teamwork oriented,
highly recommended.
Alien Swarm : An overhead co-op mod where you have to kick some Alien asses. For fans of Alien Shooter. Also features single player campaign!
LinUT: winter is coming... Developed by some friends, this is a penguins themed mod: you have to grab ice and construct your igloo! But the other team is here to do the same, the fastest wins. Let's throw some snowballs!
BTW: some parts may be in French.
USkaarj: RTS? In my UT2004? Yep sir. Go test it, it's worth a look
The Soulkeeper : A fantasy driver mod, with several classes, magic spells and swords, leveling and everything. I had a really fun time playing it with buddies as well. Their website isn't available yet (they're creating an independent game), that's why I'm linking the ModDB page.
Air Buccaneers: hot air ballons, pirates... very original, atmospheric, strategic and quite fun.
Troopers: Dawn of Destiny: Star Wars epic battles, on air and ground!
UnWheel : As its name suggests, it's a car racing mod. Very polished, it looks really professional, by the way.
Chaos UT2: Evolution: A shitload of weapons and items added, insanity guaranteed.
Unreal 4 Ever 2004: The sequel of the wonderful Unreal4Ever for UT99. Shitload of weapons as well.
Gunreal : A huge weapons modifications. Fucking insane.
Mutators:Node Siege: a gametype which creates a mix of Assault/Domination on Deathmatch maps. As the node is placed randomly, the games are sometimes unbalanced.
List not made by me.
