Gizmo DikuMUD allows multiplay of up to 4 characters simultaneously, but also offers benefits for characters with a SOLO flag.

This mud has been around for a long time, and has a friendly and dedicated playerbase.

There is tons of unique and original content to keep you playing for years.  50 mortal levels, and a system to increase hp/mana/mv.

Rank system based on fame aqcuired by decapitating the heads of strong monsters.

An undead class system for those who have reached a higher level of gameplay, with 50 additional levels and original skills/spells.

A PK arena for players to test their strength against other players.

This is a very fun mud and can be quite addicting to those who begin advancing through the ranks.
