Welcome to Castle Siege.

Engage in epic team-based battles! Attackers must breach the fortress using explosives, breakable blocks, and sheer force to slay the King NPC. Defenders must repair the walls, hold the line, and protect the King until the time runs out. Earn gold, visit the team shop, and claim victory!

This doesn't include the plugin.

Installation:

When you download the file you'll get a .zip file, inside you'll find a .schem file as well as a folder called world. If you want you can just put the world folder inside of your minecraft server root folder or you can use world edit to import the map in to your world of choice. In that case you want to go inside of /plugins/worldedit/schematics folder and put the schematic file (.schem) in to that folder than use the world edit plugin to load the schematic and place it in the world.

When you enter the world, the spawn area is at 0 100 0 location.
