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 a0.8.10 - Release notes:

Bug fixes:

  1. Min requirement for Java is now 8 or more.
  2. Java 9 issue - sun 64 decoder should be fixed now
  3. Fixed event when pirates fighting each other would still shoot you instead of ignoring you.
  4. Fixed a bug when server would majorly lag, if some NPC would get out in space.

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.
