One last word

CONGRATULATIONS! You solved ATOC: Prelude!
But remember, there is something we didn’t mention in this walkthrough.
There are a few items, within the game, we never mentioned. They are not needed to complete THIS game but… maybe you could find them useful in the future.
Try to give a more accurate look around if you didn’t find it; if you did… try not to tell it around 😉
Have fun!
