Killing Floor in UDK

[Psofus]

Greetings.

Me and some friends have recently started workin' on the new UDK willin' to make a game of our own. We have a Coder, a Maper and a 3D artist and we are all trainin' at the same time. For the sake of trainin' we want to "port" Killing floor in UDK just to see how a mod like that is built.

My question is if there is anyway I can import or make similar Volumes to KF and/or import some textures to UDK from Ued3 ?

If not, can anyone provide me with some information/tutorials on how I can make my own Volumes similar to the KF ones?
