UT2004 Total Conversion Mods?

What are some of the best mods for UT2004? I am going on vacation for 15 days, and plan on getting some of the best mods I can while I am gone so I have something to burn time with.
So far I got:
Alien Swarm
Air Buccaners
DeathBall
FragOps
Red Orchestra
Rocketer
Domain 2049
Chaos UT
and I cant think of any others I have...

I am really looking for something that is more single player oriented or has good bots for it... FragOps bots are so gay they always get stuck together.

Sounds pretty good to me. I was on the development team for an original UT mod called "Unloaded", which in my opinion is very similar to Alien Swarm. I guess AS works fine in single player, although it will become significantly difficult in places. Have you looked around at Planetunreal.com?

kk, noob questions

what are these mods? i got the game and beat it, but theres nothign else to it. these add anything or are they like skins?

They kinda like game expansions that arn't made by the original developers. Lots of games have them like D2, you get new quests and monsters and the whole look of the game changes, there's viking mods and all sorts of crazy stuff. I don't know any of the names cause I never got into them.

where can we get these mods, what would make d2 another year in my life, lol its like a bad habit you just cant kick
