The Hidden Chamber

An old vault, a forgotten cellar and an abandoned train station platform: Perhaps you could have guessed that something hidden had been slumbering deep beneath the train station for decades.
Possibly the precious secret was extremely well guarded. There would certainly be good reasons for that: If the indications of the presumed treasure prove to be true, history would have to be rewritten. And some museums around the world could mothball their best exhibits.
Do you still dare to try to uncover the mystery of The Hidden Chamber? Then prepare yourself. Whoever is brave enough to dive into the catacombs of the train station, will hardly believe their senses at times. And if your bravery actually will be rewarded, is anything but certain.
