- Armageddon is a highly modified DIKU MUD designed solely to provide a roleplaying experience against the setting of the harsh desert world of Zalanthas. Armageddon is as focused on serious roleplay as any MUSH; but it combines that roleplaying focus with the hard-coded realism of a DIKU MUD. Players are required to maintain a high level of roleplay at all times, and our standards are demanding.www.armageddon.org
