Build and Shoot

Hello, I would like some help on my new server in terms of making it an arena server. I tried 'ctf and 'tc' mode and they worked, but I cant figure out how to make it an arena server.
I am planing on creating a 'Timesplitters Map' for arena and I am not quite sure how to make blocks disappear and make the round end etc,. (like in arena).
Thanks for your help,

maps need to be configured for arena in order for the server to work
