Find the Academic, Bony and Crystalline holiday secret gifts.
With this achievement there are 3 gifts scattered across 3 different levels which you all have to find and collect in order to unlock the achievement.
The completion time is around 20-30 minutes if you rush through the levels and ignore all experience vessels and enemies. Of course the time increases when you actually play the game properly and enjoy the scenery, which I highly suggest. :)
