It begans when the 2 games were free on the Humble Store, there’s 1 month ago debating whether there were new games on the way or just a finished version of “The Hobbit” (It covered the2 firsts movie but never promised a DLC for the final film.) But it turns out it was just a last chance for people to get the games before it dissapear from the store.

You can find the games on Steam but without a purchase link.
If you already own these games, they are still playable.
