Description:
Multiplayer Hardcore is a plugin I created to get the full experience of Minecraft's hardcore mode with friends. As soon as one player dies, everyone is kicked with a message that shows the victim's cause of death, and the world is automatically replaced with a new one. No server restart is required, players can jump right back in after a death on a newly generated world.

Setup:

1. Download the .jar and place it in your server's plugins folder.
2. If you have worlds and/or items you don't want to lose, create a backup.
3. On next startup, the plugin will automatically create three worlds for you named hardcore, hardcore_nether, and hardcore_the_end.
4. That's it! The plugin will take care of world resets for you and force all players into the hardcore worlds.
