I just purchased the Elysium Edition because I enjoyed the Chapters 1-7 I played a while back. However, I am confused. The only thing I see for Days 1-12 Elysium Edition is for Android, and I am playing on PC. Could I get any guidance on what I need to do?  

Edit: And I do see the Free Editions Day 1-12 for PC, is that the one im supposed to do?

It's the update files that you need. They're provided separately, they're not one big Day 1-12 update.

There should be a Days 12-13 Elysium Edition download available. Do you see it?

okay yes! Thank you very much. I seen it, but wasn’t 100% sure on what was needed. Thank you for the reply! 

I'm confused about this as well. Do you download the "Free version" and then the Elysium Update?
