Content update at last!
There's a new game mode available, which unlocks a new area to explore. A new puzzle leads to an alternate ending and achievement!
Of course, there's a trick to enable that new game mode.
All I can say is that you'll need to give some parts to get a new one.
Enjoy!
Day of the Dead Update!
