Major Features:

  • Terraformation

  • Interstellar Ship

  • Constant Acceleration Flights

The journey was long and arduous, but we’ve reached our next destination! The terraformation system is up and running. Now you can change all the solid planets’ terraformation parameters to make them habitable, and see how they change over time! You can also build an Interstellar Ship and send it on interplanetary missions (we can’t visit other systems yet)! These projects will take centuries to complete, but they’re worth the wait!

Changes:

  • added terraformation parameters, facilities, researches, and visualizations

  • added the possibility to transfer resources into object’s deposits

  • Terraforming Mars and Interstellar Ship contracts are now completeable

  • added constant acceleration flights (Brachistochrone transfer)

  • changed the research tree into a linear one

  • added terraformation related contracts and Exoplanet Search contract

  • added color coding for asteroid pushability

  • cyclical missions can transport humans and end upon delivering specified amount of resources

  • optimized dependency of facility on crew and power

  • rebalanced power facilities

  • rebalanced costs of interstellar ship

  • rebalanced asteroid pushing

  • rebalanced resource deposits on certain objects

  • added several pieces of trivia

  • expanded drag and drop functionality

  • changed camera work and focus in certain situations

  • adjusted fastest and optimal flight suggestions

  • enabled Steam Cloud

  • added several tooltip strings

  • removed possibility to send crewed flights with rotary launcher

  • minor visual and UI adjustments

  • added missing arts, strings and sprites

Fixes:

  • fixed construction progression being resetted after loading a game

  • fixed Earth running out of water within a century

  • fixed spacecraft disappearing from objects upon completing a mission

  • fixed spacecraft dropping cargo during the gravitational assist maneuver

  • fixed missions not launching with progress exceeding 100%

  • fixed negative population on objects

  • fixed several optimization issues

  • fixed several exceptions

  • other minor technical, visual and UI fixes

Known issues:

  • saves files from previous versions WILL NOT WORK in the current build - please revert to a previous build if you want to continue your gameplay

  • constant acceleration flights may sometimes require exorbitant amount of fuel

  • some habitability parameters may occasionally display wrong color coding

  • Power Consumption might not always be displayed properly

  • Steam Cloud might encounter some issues

Have fun in space!
