No pause. Ever.
Pausing is switched off for the whole fight, for both of you. Vent the fire, reroute power and fire the volley while your opponent does exactly the same. Every second you spend thinking is a second they spend shooting.
Features
FTL's systems, weapons and crew are all still there. What changes is that the opponent is a person, a server referees the fight, and nobody is waiting for you.
Pausing is switched off for the whole fight, for both of you. Vent the fire, reroute power and fire the volley while your opponent does exactly the same. Every second you spend thinking is a second they spend shooting.
Neither player's game decides who won. A dedicated match server simulates every shot, hit and system 60 times a second, using a transcription of FTL's own code that is checked against recordings of the real game. Both screens show the same fight.
The enemy's interior and crew, their weapon charge and their reactor only reach your computer once your sensors are good enough to show them. Upgrade sensors to see more; until then, that state is never sent to you.
All 28 player ships are allowed, and any hull can fight any other. Start with exactly 10,000 scrap in a full, searchable store of weapons, drones, augments, crew and systems. Flagship and enemy-only gear is left out, and missiles and drone parts stay at your hull's defaults. Save the result as a loadout.
Press QUEUE and the server checks your build, then pairs you with the next captain who is ready. You both accept a MATCH FOUND prompt within ten seconds, and the fight starts.
Offer a draw at any point; if you both do, it ends even. If your connection drops mid-fight you have 30 seconds to reconnect and take your seat back before it counts as a forfeit.
The core rule
You stop the universe, read every tooltip, queue four weapons on the exact room you want and unpause into a perfect turn. The AI waits politely. It has always waited.
Their missiles are already in the air, their beam is lining up on your weapons, and the shield you were about to repower just took an ion hit. Nobody is waiting. Decide now, or decide worse in four seconds.
The hangar
All 28 of FTL's player ships are allowed, and any hull can fight any other.
Any hull can fight any other. You pick from FTL's own hangar, so which ships you can choose may depend on what you have unlocked in FTL. One gap for now: the Crystal crew's lockdown ability can't be triggered yet.
Getting started
You need FTL: Advanced Edition, version 1.6.13, on macOS. It is built and tested against the Steam copy. Intel and Apple Silicon Macs both work; Apple Silicon runs it through Rosetta.
Unzip the download and double-click install.command. It patches your FTL install, keeps an untouched copy of the game data, and puts an FTL Multiplayer launcher on your Desktop.
Open FTL Multiplayer and press MULTIPLAYER. Pick a ship, spend your 10,000 scrap, then press QUEUE. Accept when the match is found, and good luck.
Download the client, build a ship with 10,000 scrap, and queue for your first match. Free, for macOS.
