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 going to grow.

But at the same time all releases are very stable and contain minimal amount of bugs.

Our steam page is ready for your wish-listing!
