Ancient Sky Castle is a smallish death match map made by Deadbankclerk and Mr Damage.
The map is set in the ruins of an ancient temple in the sky. It uses all custom textures and a custom sound.
It has twelve player spawns and ample weapons and items.
It is currently in rotation on several Kingpin servers.
Just unzip the files to your Kingpin folder and they will be placed in the correct locations.
