STORY
A young man has spent his life suffering from a mysterious memory problem wherein his recollections of the past are not consistent with reality. Throughout his existence, he has suffered the ridicule of his teachers and classmates because of his strange problem.
His path takes a turn when he is contacted by an enigmatic figure who maintains that the young man is, in fact, possessed of a secret and incredible destiny.

The figure, who calls himself Dr. Quantum, says that his memory problem is not a problem at all, but rather is an immunity... a special power pertaining to the very fabric of time itself. He enlists the young man to take part in a great adventure against a deadly adversary, and to use his powers and intellect to solve some of the most dangerous conspiracies, puzzles and mysteries in our history. Mysteries that will, when solved, unlock some of the most fundamental and fascinating Truths of the Universe itself!
GAMEPLAY
The game is a streamlined, modern take on the Alternate Reality Game (ARG) genre. Each puzzle is presented as a titillating combination of text, images, sound, video, and 3D objects. The puzzles lead you on through the storyline, integrating and building upon the mysteries you´ve already uncovered, and revealing deeper and more complex enigmas that will amaze, thrill, and even scare you. Be warned: the solutions to the puzzles are not easy to discover, and may be hidden in history, obscured by cryptograms, embedded within steganographic images, concealed within riddles, shrouded in history, or guarded by any number of other dark concealments.
The game intends to connect you with reality, so you are encouraged to use any real-world resources available to you: Internet, Books, Library, Encyclopedias, ANYTHING! Well, except Spoilers, for obvious reasons :P

You are only limited by your imagination.

Think laterally, think outside the box, home in on information like a librarian with a neural net co-processor... do whatever you must to Move Forward and Solve the Mysteries!

Come, Take a Stand! Find the Truth. Reveal the Secrets of the Universe and Repel The Temporal Invasion!
