Instructions:

 - DM-ApocalypseReactor.ut2: The actual map. Unzip this file into your "Unreal Tournament 2003/Maps" 
Folder.

 - Readme.txt: The file you are reading. Makes sense doesn't it?

 - LightsOfFire.ogg: This is the music file used by the level. Unzip it into your 
Unreal Tournament 2003/Music folder. 
NOTE: This is NOT nececcary to let the map run properly. I chose this song to run 
in my level, but if you don't like it you can let it be.

 - Screenshot.jpg: This is only needed for the staff of Unreal Playground. 
You don't have to do anything with it, but you can always unzip it if you like it... ;-)
