here is a list (imo) of some of the best maps to grace UT3, these are either cooked from maps made for the PC or for the PS3..
these are all deathmatch maps, if you want CTF or the warfare maps go visit
www.ut3mods.com thats where these links come from.
you could go through the epic forums like i do and grab the beta versions, but if youre in no rush then its one site.. and thats UT3MOD.com. there is no need imo to visit any other site. its PC and PS3 friendly, so there is no problems, even gives you a tutorial (

Shipment (CoD4 map).. remade UT style, and works great imo...

Harbor.. an amazing map i believe just made for the ps3, who ever made this is just way out there in terms of map making. i love this map.

Tiberium.. what can i say? its green, its fast it looks and plays fantastically well, certainly one to download.

Orbital Destruction.. this map is certainly different, in a "in space no one can hear you scream" kind of way. very cool map.

FlatWars.. my fav map of all. this is bloody great fun. ever since time begun and people have been making maps for online gaming, someone has ALWAYS mad a maps of their bedroom or kitchen, well someone has made one of their bedsit! you can get bedroom and bathroom maps on ut3mod.com, but for now i give you FlatWars!
