All eventsPlayers around this dateRead on Steam

For details on how to switch to the experimental branch, see Release 15 patch notes.

This update should finally address the issues with movement latency, especially at higher framer rates.

In terms of new content, there are a variety of new ship and station modules that can be unlocked both through normal research and by trading at the Trade Outpost. Some highlights include a larger 2x2 bridge for piloting ships from, and stackable elevators that can move both players and items that should give you more flexibility when designing vertical bases.

All of these new features and improvements should be available without having to start a new save, just visit the Trading Outpost to check for the new purchasable blueprints, or check in the Tech Tree.

Features:

  • Added stackable elevators that transport both people and items.

  • Improved movement latency.

  • Added the Small Bridge, a new piloting module for ships.

  • Added 1x1 and 2x1 Armour Slope modules.

  • Added Ship Frame and Ship Frame Slope modules.

  • Added 2x2 Corridors and Adapter station modules.

  • Added 2x2 Station Modules variant C.

  • Plasma cannons can now be mounted underneath ship modules.

Balance:

  • Updated the Ship Habitat model.

  • Updated the Station Lift model.

  • Updated the Slipstream Drive model.

  • Ship Armour renamed to Armour Wings.

  • Ship Armour Wing now unlocked at the Trading Outpost instead of through research.

  • Added a sound effect when using the Station Lift.

  • Ship Armour Wing 2x1 Hull increased 15 >> 20.

  • Ship Armour Wing 2x1 Mass increased 3 >> 6.

  • Ship Armour Wing 2x1 now requires 10 Hull Plates to build.

  • Large Station Modules no longer require Computation Science to research.

Bug Fixes:

  • Fixed movement input being interrupted when picking a machine to build.

  • Fixed the colliders on the new ship windows and Captain’s Quarters.

  • Fixed ship blueprints not being loaded in the shipyard designer.

  • Fixed the Teleporter being offset when placed.

  • Fixed issues with the models for the Ship Window Habitat and Corner Window.
