# Icesus MUD

> Icesus is a free multiplayer text-based RPG (a MUD, multi-user dungeon) set on a frozen planet, online continuously since 1995. It is run by the Finnish non-profit association Jää ry and volunteers: no subscription, no purchases, no pay-to-win. You can play instantly in a web browser (Play in Browser, at https://play.icesus.org/) with no download, or with the official Mudlet package. The browser client has built-in screen-reader support.

Key facts: 65,000 rooms across a living outworld with line-of-sight vision, seasons, day/night, and rivers that freeze and thaw; 27 playable races; 17 main guilds; an extensive reincarnation system that lets players rebuild their character (race, guilds, stats) as they learn, planned with the character builder's reincarnation view at https://icesus.org/character-builder/?view=reinc; tactical party-based combat where solo play is also fully viable; deep crafting chains and a player economy; player-built provinces with council governance, cooperative PvE settlement building live since May 2026; mainly PvE; roleplay supported but not enforced; dozens of players online regularly, an active Discord community, and an annual in-person MudCon meetup.
