This map was not created or designed by me. It was given to my by someone on the Zone. DO NOT ASK me if I know how to map Trial maps. But I have found information that may help you.
Any map under these names will be read by the system:
•Trial Costal Map
•Trial Multiplayer Costal
•Trial Multiplayer Team Islands
•Forgot, but there was a fourth one...
They wont run though, that is the problem. ES probably has another editor for these maps.
