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 a0.8.7 - Release notes:

  1. Trailing mode bug fixed(essential for final boss in the story mode).
  2. (For modders) Modify ship event can now rename ships.
  3. (For modders) Sector_ships_present/absent conditions now have the ignore_class field, to ignore certain ship classes

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


Currently the game is being redesigned from a space game into an underwater submarine one.

The final game will be an MMO, and will have a lot better art style.

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.
