How To Access Other Branches/Builds

Published on Wednesday, May 31, 2023 By RammaStardock In GalCiv IV Support

Hello all,

With the update from v1.51 to v1.55 not being save game compatible we wanted to take a moment to provide simple instructions on how to access either branch of the game at will.  

There are 3 builds of the game:

  1. default - The current released build
  2. version_1.51 - Version 1.51 for those who want to play older save games.
  3. insiders - For those who want to play pre-release updates and help test new features/fixes. These builds eventually become 'default' on release.

How to opt-into a specific build:

On Steam:

  • Select "Galactic Civilizations IV: Supernova in your Steam Library list.
  • Right-click and select Properties.
  • Select the BETAS tab.
  • From the dropdown, select the desired build and exit the dialog.
  • Steam should pull down the changed files; if you ever want to go back, do the same as above but select
    default (or None).

On Epic For Insider Build:

To enable the patch, please do the following:

  • Open the Epic Launcher
  • Select "Galactic Civilizations IV: Supernova - Insider's Edition"
  • Install and play!

Epic does not currently support old version downloads.


Please note: The opt-in (Insider Build) is an early preview of the next update, and you might experience bugs or other issues.
