Edit mode:
Start the game with bzone.exe /edit. You'll be asked of something 
which doesn't apply to you (unless you do edit your own maps) 
when in-game, you can press Ctrl-A to freeze time, and now you can 
get away / to and even create object (such as the RAVE GUN!) For more 
info on what you can do with this, read edit\*.doc (Disabled in multiplayer).
