I found 3 really nice DM maps i would like to share with all of you
DM-Ostheim
This map is from the same maker of Ostwerk(sp?) the only difference is i think this one is better. It's got great lighting and archetecture and the bots play the map pretty tight. It can get a tad laggy but not that bad. I recommend you pick this up and give her a try, especially if you liked DM-Ostwerk.
DM-Blue
This map is set in a space station underwater. The maps textures are of course that of a space station but this map uses alot of blue lighting and blue type material (well it is water afterall) and not only does it look good, but it gives of some nice lighting effects. It's unique that's for sure. Bots play it good, i've read reviews that the bots get stuck somewhere but i didn't notice it though.
Dm-Oros
This has to be the best Egyptian themed UT map i've played. The Architecture is really good, the lighting isn't too bad, but not too great but man does the map look good. Bots play good as well. It gets a little laggy when your outside of the temple looking directly at it. But it's still a nice map you should checkout if you haven't already.
P.S. - Yeah the screenshots suck, i'm too lazy to post any myself, oh well.
