THERE ARE A LOT OF MAPS HERE...BKSE IS A SKIN PACK,,READ README 
FILE BEFORE INSTALLING,,,THESE ARE NOT INSTALLED ON NEWBIES SERVER
,,,,ALSO IF YOU INSTALL THESE MAPS(A LOT OF THEM) BOTMATCH WILL TAKE
SEVERAL MINUTES TO START UP(IT HAS TO SORT MAPS),,,I SUGGEST U
PUT THESE IN A FOLDER AND INSTALL THEM AS NEEDED IF YOU PLAY BOTMATCH 
OFF LINE...I HAVE THEM ALL INSTALLED BUT I DONT PLAY OFF LINE...
IF YOU USE WINDOWS EXPLORER AND CLICK ON A PARTICULAR MAP AFTER
INSTALLING THEM IT OPENS UNREAL NORMALLY AND YOU CAN PLAY THE MAP.

windows explorer.  some are self extracting files and when it states
the unzipp target it may say c:\unreal   and if u have gold add gold to
the end of it before unzipping,,,in other words watch where u send the 
files...
