Paroxysm is a playable early-alpha text-based multiplayer RPG (a MUD). Adults only.

A modern supernatural dystopia. The gates to Hell opened. Almost half of humanity died. The gates closed. What remains is under the Cortex — a world government built on surveillance, containment, and control. Player-led societies form in the wreckage. The supernatural is real. Under the Cortex, humanity endures.

Paroxysm is a world built by its people. Systems are unfinished. Bugs exist. The world is still forming. We are building it in the open.

Connect (any MUD client): mud.paroxysmrpg.com port 3000
Website: https://paroxysmrpg.com

Adults only (18+). Adult themes, including erotic roleplay between adult characters, are permitted. Nothing involving minors.

Disclosure: AI tools were used in coding both the website and the game, and in drafting this post.

Small update for anyone who found this thread:


The world itself hasn't changed. WWII ended when a portal to Hell opened, almost half of humanity died, and the gates closed. The Cortex has watched everyone since. Vampires, werewolves, demonborn and Cortex enforcers fight over factions and territory, PvP is on, and AI Champions compete alongside players.

Adults only (18+). Early alpha. AI used. We'd love to hear first impressions here or on Discord: https://discord.gg/Hkx8rcj4k6 . Site: https://paroxysmrpg.com

Halloween update, from under the Cortex.

Paroxysm now has an itch.io page, if that's where you keep track of games: https://paroxysmteam.itch.io/paroxysm

Nothing else changes on your end. Play in the browser at https://paroxysmrpg.com/play/ or point any MUD client at mud.paroxysmrpg.com:3000, make a character, and find a scene.

For anyone new to the thread: WWII ended when a portal to Hell opened. Almost half of humanity died before the gates closed, and the Cortex has observed, contained and controlled everyone since. You can play a vampire, werewolf or demonborn, or enforce for the Cortex. Factions hold territory, PvP is on, and AI Champions compete in events alongside players.

Adults only (18+). Early alpha, text only, and the world is still forming. AI used.
