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.

Version a0.8.19 - Release notes:
This release is made mostly by modders requests, while I'm working on the steam version of the game.

Modding features:

  1. World gen events are now sorted by name before execution
  2. Added possibility for conditions related to projectile events to be based on both the target and shooter ship at the same time.
    Ex. If target ship is missing 5+ hull, and origin ship has 1+ drone, trigger event
    <condition type="SHIP_SYSTEM_PRESENT">
    <!-- Check_target_ship and check_shootership are used only by events -->
    <!-- that are triggered by ship projectiles on hit. -->
    <!-- Available in all SHIP... events. --> <condition_param check_target_ship="1">
    </condition_param> <condition_param check_shooter_ship="1">
    </condition_param> <condition_param system_type="SHIELDS">
    </condition_param> <condition_param qty="1"></condition_param>
  3. Added possibility to jettison items from ship's cargo via events.
    (ex. If npc ship accidentally picks up cargo, spit it back out)
    In the MODIFY_SHIP event:
  4. Added possibility to remove specific instances of ship ai instead of all of the same type.
    Ex. remove one event_trigger without removing the other event_trigger.
    When adding an AI give it some id:
    <ship_ai_param ai_id="abc123"></ship_ai_param>
    Then in the modify ship event use:
    <event_param remove_ship_ai_id="abc123"></event_param>
  5. Modify ship event <event_param hyper_jump="100:200"></event_param>
    No longer requires the ship to have a functioning Hyper drive
  6. In the SERVER_VARIABLE_PRESENT/ABSENT condition - added a new parameter.
    <condition_param any_value="1"></condition_param>
  7. Added [MOB_POS] and [SHIP_POS] placeholders that can be used in events and conditions.
  8. Added [PROJ_POS] placeholder that can be used in events and conditions tied to projectile hit events.
  9. In the Spawn ship and Spawn NPC events the pos parameter can now have a reference to a variable, including the mentioned above.
    (Previously it was expecting a strict XX:YY value)
  10. In the ship editor you can now press C to see the cell coordinates
  11. In the MODIFY_SHIP_EVENT added a new parameter:
    If set to 1, then it passes only the ships that were modified in the current event to all chain events.
  12. Changed the core event files to not use a hard-coded ship name Falcon.
    Now it uses the name that is set in the VAR(PLAYER_SHIP_NAME) variable.
    This allows the modders to make own player ships.

Bug fixes:

  1. LEVEL_LOADER AI - was broken
  2. NPC_EVENT_TRIGER AI - was broken
  3. SCAVENGER AI - was broken
  4. SHIP_CARGO_PRESENT/ABSENT condition - was broken
  5. SECTOR_SHIPS_PRESENT condition - crew parameter was ignored.
  6. Hacking page - buttons alignment on higher resolutions - was broken

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.
