Hey guys.
I've seen some requests for access to older versions of the game, and while it's a bizarre request, for the most part, we have enabled this option. :)

If you want to access any of the previous versions, please go to your library and do the following:

• right-click on Serious Sam 4
  
• select properties
  
• select the "betas" tab
  
• paste the password to the little empty box
  
• select the version of the game you would like to play

The password to unlock older branches is:

This will roll the game back to the selected version.

Please keep in mind that older versions will be less stable than the current one in most cases. Also, saves are not backward compatible.

Much love!
Danny
