Archive server
From FroobWorld Wiki
The archive server hosts old FroobWorld maps and allows players to explore previous builds. A number of commands are provided to facilitate exploration of the old maps, including the ability to teleport to old warps and homes. All retired maps from map 5 are available to explore. There are no surviving backups for older maps.
The archive server can be joined using the IP archive.froobworld.com
or using the command /server archive
in the main FroobWorld server.
