We'd like to remind everyone that
you don't have to buy the Season Pass if you have bought the game before its release!
If you have bought the full game, you own the full game. The new episodes will just download as an update.
There seems to be a little bit of confusion and we apologize. The season pass is meant for those who have only purchased episode 1, which is now possible.
Unfortunately, we cannot take out the option to buy the season pass for people who have the full game. This is handled by the store.
