Hi there prospectors,

Welcome to another unstable update with a significant overhaul to improve the flight model and boats. We've made quite a lot of changes here that we're pretty confident will offer a much better experience when building and flying planes or sailing boats. Your existing plane and boat Techs may be markedly improved or possibly worse because of the changes that have been made and may need refining.

We've added some example planes, boats and amphibious planes to Creative Mode for you to try out. There are also some new blocks in this update to allow greater flexibility when placing the position of your plane wings for example to finesse your Tech builds.

Thanks as always for the invaluable feedback and bug reporting and we hope you enjoy playing this update.

⚠️Please note: This update is on Steam beta branch ttw_unstable - Work-in-progress version and may be unstable in places.

In the run up to promoting the latest unstable update to the default version of TerraTech Worlds, we want to improve the quality of the build by finding and fixing as many bugs as possible and refining how the game is balanced.

To play the unstable:

  • Right click TerraTech Worlds in your Steam library, then select the "Properties" option from the drop down list.

  • Now select "Betas" and then select the "Beta Participation" drop down box.

  • Select the "ttw_unstable - work-in-progress version" from the drop down list.

  • Your game will now update, and you will be playing on the unstable branch.

To send us your feedback and join the community:

  • Join our discord server and select the unstable role via the #role-opt-in! channel. This will add you to the secret unstable channel where you can discuss your feedback/spoilers.

Remember to always back up your save games before switching to the unstable branch.

Flight improvements

  • The flight controls have been improved to provide better controls for flying aircraft Techs; allowing the plane to pitch, roll and yaw in a more intuitive manner.

    • When flying, the camera moves to frame the Tech centrally.

    • Added yaw controls on mouse and keyboard (Q/E).

    • Disabled the auto-trim, which was forcing planes to fly level regardless of controls.

    • Disabled mid-air steering for winged Techs.

    • Gliding with no propulsion has also been improved.

  • A flight blocks filter button has been added to the Tech block inventory to show all flight blocks.

  • Some example planes can be found in Creative Mode; behind the starting position is a take-off and landing strip with 4 different sized planes to switch to and try out.

Boat improvements

  • Boat travel has been improved to allow greater control of building and steering boats on water.

    • Introduced a greater difference in the power of different propeller blocks.

    • Rudders provide a greater ability to steer.

    • Buoyancy values for blocks have been refined.

  • A boat blocks filter button has been added to the Tech block inventory to show all boat blocks.

  • Some example boats and amphibious planes can be found in Creative Mode if you continue past the take-off and landing strip to a jetty by the sea.

New flight and boat blocks

  • SEA Relentless Duck Cab

  • SKY Two Hull

  • Sky Three Hull

  • Small Double Bubble Wheel

  • Large Double Bubble Wheel

  • Spat Bubble Wheel

  • Connector Spat Bubble Wheel

Quality of life improvements

  • The HALO Relocator has been separated out from the Tech block group of Speedometer, Altimeter and Anemometer.

  • A tooltip has been added to the bottom ribbon for toggling the display of the physics visualiser when in build mode.

  • The objectives screen now has a scrollable panel instead of the older style pagination.

  • An option has been added to the game options to "Only Show Hints Once."

Bug fixes

  • The following bugs should now be fixed in this update:

    • When picking up a stack of blocks from your Tech Yard Storage, returning them via Right Mouse Button duplicates the amount that get returned.

    • If you attach the Journeyman cab before progressing to the objective, then you must redo the objective to progress.

      • The game now retroactively recognises the completion of this objective.

Until next time, Prospectors!
