Ever wanted to play FTL with your friends, as a team, in a coop multiplayer run?

Well basically Tachyon is a multiplayer version of FTL.

But with it's own engine, logic, mechanics and of course some additional features - like being able to leave your ship for example.

Also the game is made to be quite a bit mod-able, so you can create your own multiplayer adventures.

You can host your own local server for a private coop game with your friends. Or you can host an MMO server to roam around hundreds of thousands of sectors with other space pilots.

Tachyon is currently a WIP, so the amount of content is only going to grow.

But all releases are very stable and contain minimal amount of bugs.

Version a0.8.18 - Release notes:


  1. Full-screen option removed from settings menu
  2. Borderless window option added in settings menu
  3. Added movement propagation to improve network performance.
  4. It is now possible to teleport players between multiple owned ships.


  1. There are now less NPCs overall, but they are harder to kill.

Bug fixes:

  1. Hacking page was broken on high resolutions.
  2. Finally fixed the Space Disorder Syndrome?
    (The oldest bug that made NPCs vent themselves into space and die there)

By default the game pack contains events configured to create a coop story mode universe. But several modders are already working on an MMO mod. You can get more details on this on our Discord channel.

Also a new story mode is being developed. It will contain a lot more different random events.


Currently the game is being redesigned to have it's own and better sprites.

Anyone who donates >=5$ will get a free copy of the game once it's out. It will be sent to the E-mail address that is linked to the donation.
