RECENT SUBSPACE TRAFFIC

  • 2026.04.26 Public access opened. The browser client at play.stmud.com is now live for new commissions. Telnet diehards can still raw-jack via stmud.com 4000.
  • 2026.04.25 Academy revised. Cadets now run a hands-on bridge sim, a tactical exercise, and a real away-mission skill check before commissioning. Veteran accounts skip straight to their starbase.
  • 2026.04.20 Crew systems online. Captains can now build a real bridge crew — bridge officers carry aptitudes, sustain injuries, and stay dead. Pick your XO carefully.

Setting

The galaxy after the cease-fire.

The big war is over. Nobody won. Treaties were signed in stations that smell like coolant and old smoke, and a hundred million junior officers got handed a ship and told to keep the silence.

STMUD is set in a parallel-canon Trek universe a few years after the last great power conflict. The Federation, the Klingon Empire, the Romulan Star Empire, and the Cardassian Union all walked away from that war scarred and short-handed. Patrol grids have holes. Border zones are technically "demilitarized." Pirates and salvage crews have learned where to look.

You play a fresh commissioned officer — Starfleet Ensign, KDF bekk, Tal Shiar operative, or Cardassian garresh. You graduate the academy with one starter ship, a small bridge crew you'll come to either trust or bury, and a galaxy full of people who don't yet know your name.

What you do with that is the story.

What the universe is

  • Persistent. Player ships, crew rosters, and reputation persist across logins. The universe doesn't reset.
  • Player-driven. Every commissioned ship you see in the docking bay was named, captained, and crewed by another player.
  • Multi-faction. Federation, Klingon, Romulan, Cardassian. Same galaxy, different rules of engagement.
  • Crew-centric. You don't fly a ship — you command one. Officers have names, aptitudes, and they will die if you push them too hard.
  • Hard but not punitive. Death of a single officer is a setback, not a wipe. Losing a ship is a story; losing all of them is a chapter.

What it isn't

  • Not canonical. We don't claim continuity with any aired show or licensed novel. Treat it as a parallel timeline.
  • Not pay-to-win. Free, no microtransactions, no premium currency.
  • Not a clicker. You'll type commands. You'll read text. You'll lose people.

Pick your colours

Four factions. Same stars. Different orders.

Each faction starts you at a different home base, hands you a different starter ship, and judges you by a different code. Switching sides isn't easy.

UFP

United Federation of Planets

Exploration, diplomacy, "boldly go." The Federation handed you an ensign's pip and asked you to find new life.

Home base
Earth Station McKinley
Starter ship
Danube-class Runabout
Plays like
Diplomatic, science-leaning, peace-through-strength
KDF

Klingon Defense Force

Honour, glory, the slow grind of an empire trying to remember why it fights. Take a ship and bring back a story worth singing.

Home base
Ty'Gokor Station
Starter ship
Toron-class Shuttle
Plays like
Aggressive, melee-friendly, reputation-driven
RSE

Romulan Star Empire

Cloak, strike, vanish. The Tal Shiar runs a quiet war the rest of the galaxy thinks ended years ago.

Home base
Romulan Staging Base
Starter ship
Kestrel-class Scout
Plays like
Stealth, alpha strikes, intel work
CU

Cardassian Union

Discipline. Order. The bureaucracy that survived. You were assigned a patrol; do not disappoint Central Command.

Home base
Cardassian Orbital Station
Starter ship
Hideki-class Patrol Ship
Plays like
Methodical, tough-armoured, tactical

Hardware

Hulls you'll be sleeping in.

Each faction's starter ship is a working light combatant. Bigger, faster, deadlier hulls show up after you earn — or take — them.

Danube · Runabout

Federation starter

Small Starfleet utility hull. Modular, well-armoured for its size, decent at everything and great at nothing. The runabout that taught you what a console feels like in your hands.

Toron · Shuttle

Klingon starter

Ugly, fast, and personally offensive. Twin disruptor cannons mounted on stubby wings. Klingons consider it a ship; everyone else considers it a problem.

Kestrel · Scout

Romulan starter

The Tal Shiar's pocket warbird. Cloaks. Strikes once, hard, with the alpha-strike bonus. Then runs away. Don't get into a slugging match.

Hideki · Patrol

Cardassian starter

Boxy, methodical, hard to kill. The Cardassian answer to "what if a tax form had phasers." Excellent armour, fair sustained fire, mediocre top speed.

Miranda · Light Cruiser

Federation upgrade

The workhorse. Shows up in every Federation deployment. You'll requisition one when McKinley decides you've earned promotion to lieutenant.

Galor · Heavy Cruiser

Cardassian upgrade

The flagship of any Cardassian patrol that means business. Wide spinal phaser array, dense armour scheme, takes a beating.

Galaxy · Explorer

Federation flagship

Long-range, full crew complement, every department has a deck. The ship you want when the mission is "go look at something nobody has ever seen."

Other classes — Excelsior, Bird of Prey, T'Liss, Nor — appear at higher ranks. Run shipyard at any starbase for the full registry.

Quickstart

From "what is this" to "report to McKinley."

  1. 1

    Open the client

    Go to play.stmud.com. The browser-based client handles login, the LCARS bridge UI, the deck map, and the consoles for you. No install. Works on phones (iPhone tested at 375px width).

  2. 2

    Create an account

    Click + CREATE ACCOUNT. Pick an account name (4–12 letters), a password, confirm it. The server creates the account and drops you straight at the main menu — no email, no waiting.

  3. 3

    Pick a faction and roll a character

    Pick SELECT / CREATE CHARACTER, type a character name, choose a species and a department. The academy spawns. Your first character runs the tutorial; subsequent characters on the same account auto-skip.

  4. 4

    Graduate and claim your ship

    Walk through three small exercises (open a console, give a captain order, react to an away mission). Type graduate. The transporter takes you to your faction starbase. Walk south to the docking bay, type requisition, name your vessel, and walk down to board.

  5. 5

    Find people. Or trouble.

    Run missions at any console for paying work. Run scan from your bridge to see what's around. Run course <system> to engage warp. Make sure you have a crew with you before you pick a fight.
