How 2 install maps....

First unzip the downloaded file. (you need winzip for this)
Next go the the place were u unzipped the files. (minimize this folder)
Then open go 2 my computer
C:\ drive
Unreal Tournament
and u will see a list of folders.
double click on the maps folder
now maximize the folder were all the unzipped files are. click on DM-Burning Worlds.unr and CTF-Burning Worlds.unr and drag them into the unreal tournament maps folder.
your almost done. next click back on the ut maps folder and open the textures 1.
drag all the other files into that folder except for the readme file which will explain everything that is written here.
Now open your unrealtournament game and when u make a game the downloaded map will be in the map list although there will be no picture to show it but it will work. 

Happy gaming :D
