[The Plague of Death]

he could do that, but the server is running remotely, a rented server, at least that is what i have gotten from his post. But to answer the question, without actually going into the srver to change the map, yes it is possible.

Open Spearhead.
Open console
type "rconaddress xxx.xxx.xxx.xxx" without the " where x = ip
type "rconpassword xxxxxxxxx" without the " where x = password
type "rcon map whichever map you want"


and walla, the map is now changed.
