Hello fellow preppers!

The engine update is now live.

It was very challenging to us to migrate the whole game from the old engine to the new one. We really hope it went well :) We performed a lot of tests and playthroughs and we experienced no issues. But it is possible that we missed something. Due to this fact the old version of the engine is still available on the "Legacy" branch. Please find instructions below how to activate the old engine if anything wrong happens to the new one.

Also - we will be fixing all the issues that might happen on the new version of the game. Please report anything to us via email: or discord:

If you want to go back to the previous version of the engine please follow the steps below:

  1. Go to your games library and right click on the Mr. Prepper's game and select properties option.

  1. Navigate to the "Betas" tab and select "Legacy" from the drop-down list

This will downgrade your game to the previous version of the engine.

We will continue working on the game and fixes. New engine should make it a lot easier from now. I hope you enjoyed the game so far.

Have a good play, preppers!

Truly yours,
Rejected Games
