nikontunnus: Yes, it includes them all so far! :) You should play the newest version for less bugs. (Actualy when I download it it is still files for version 2.6.0.8 and not 3003 as it says but it still includes episodes 1-3...)

Also you should not play the old version of the first 2 chapters, some of the old versions cause a bug in episode three where you choises are wrongly remembered.

Download all three files in the same place (wierdly one of them got in the wrong folder for me) and run the download. :)

You can use this link to update your games library to the newest version, especially if there seems to be an error or you can't download the files:

Also it's good to refresh library (the link) to be sure to get the newest version of the game since they are paching it a lot now when a new episode has arrived. I'm guessing logging out and back in could do the same trick.

Have fun!
