Implementing/Testing Steam Achievements for an UNRELEASED game?

Hey lovely people,

I’m testing Steam achievements right now, and it works well for my already released demo.
BUT, I wonder: How can I implement those for the ACTUAL game, which is not released yet?!

  • In the code, I supply an APP ID
  • The game and the demo have different IDs
  • Right now, I can not test achievements in the unreleased game. Of course, I’ll use the same code from the Demo for the final game, but it feels still a bit weird not being to be able to test this pre-release…

Does anyone of you have experience with this situation?
Simon
