UT2004 mod suggestions

[babs]

I recently reinstalled UT2004 after buying it on release day and playing it about twice, and there seems to be a new mod out every day for it. I wanted to know what the fine forum-dwellers here could suggest for mods/TCs. I'm looking for the most fun stuff, and also most popular. I got Red Orchestra this morning which seems like it would be more fun online, other suggestions though are gratefully received.

Alien Swarm

Available from the download section. Good SP and MP. (top down shooter though)
