In order to fix a crash that was happening on certain laptops with Intel chips we have had to update the Unreal Engine version Empires of the Undergrowth is built on. Doing so may have some performance improvements but mostly the experience should be the same.

0.2223 Steam Cover.jpg

We’ve done plenty of testing ourselves but a change like this is systemic, so any part of the game could have issues that we’ve missed.

We are running this beta to make sure there are no hidden bugs that cropped up during the engine update, and we appreciate anyone who can spend some time testing any and all aspects of the game for problems.

If you would like to join the beta, the code is givemeextraextra. If you don’t know how to join a beta and would like to, follow the instructions below:
  1. Find Empires of the Undergrowth in your Steam library, right-click on it and choose "Properties"
  2. Choose the "Betas" tab
  3. In the box titled "Enter beta access code to unlock private betas", enter givemeextraextra
  4. After the "Access code correct" information appears, make sure you've chosen "Open beta" from the "Select the beta you would like to opt into" drop-down menu
  5. Press close - the game will now update to the beta branch.
We highly recommend making a backup of your saved games before you run an optional beta, on the off-chance that some changes cause them to be corrupted. To see where your saves are stored, see the information in this thread on the Steam forums.

Extremely Helpful Person
Extra levels now come with a description and minimap when selecting them from the menu
Is this feature also planned for the alpha demo level selection menu? (Since the level selection menu for the demo levels is similar to that of the extra levels, it might make sense also adding it there.)
