Hey everyone!

We're happy to announce that the beta for the Behaviour Update is now live on the OpenBeta branch on Steam. As always, if you'd like to participate, be sure to back up your saves!

BACK UP YOUR SAVES - Before taking part in the beta, if you have some ecosystems you love and want to test out the combat, please back them up. You can find the save files in your "My Documents/Ecosystem" folder.

ACCESSING THE BETA - Right-click the game in your library, choose "Properties", choose "Betas", and select openbeta from the list.

WHAT'S CHANGED - Check out the patch notes below:

PATCH NOTES

FEATURES
Increased creature autonomy: after learning first to swim and then to seek out targets, creatures enter a life stage in which they are more autonomous in their decision-making, attempting to fulfill their individual needs.

The following new behaviors are now available to creatures:

  • Finding shelter and resting
  • Building nests
  • Feeding on insects on the water surface
  • Gathering food to bring to their offspring
  • Playing and socializing, chasing each other or knocking stones around
  • Swimming in schools
  • Bioluminescence
  • Song
  • Pitch and volume envelopes for each note in a song are specified in the genetic code, so songs will evolve as the species does.
  • Reworked creature fertility and energy so that the odds of survival and number of offspring is less influenced by random factors.
  • Creatures now remember the locations of food seen while exploring.

FIXES

  • Improved line-of-sight checks before creatures resort to pathfinding to prevent cases where creatures swim far up because their target is behind a small bump.
  • Fixed some errors with line of sight checks that could result in creatures not seeing food/mates that actually should have been visible.
  • Fixed error where color comparisons could be incorrect when checking how well a creature blends in with its environment.
  • Fixed error where bilateria spawn preset had incorrect 4x lifecycle count by default.
