Crash landing on an alien planet you must navigate your way through an ancient factory by learning a mysterious alien language with careful observation of the functions of a variety of computer panels scattered across the factory. No boring block puzzles here, the order of the day is experimenting with a variety of computer systems and deciphering an ancient language to plunge on further into the game. No linear puzzle completion order here, either, the game allows you to wander about the factory figuring out what you can, building up your knowledge to complete other puzzles, but not in a particularly specific order.

Features:
* Over 20 intricately connected maps form a massive underground factory to explore and solve.
* Innovative language / computer panel puzzles put a new twist on the adventure genre.
* Scattered remnants of an alien civilization form a strange sort of village and unveil the history of these mysterious factories.
* Partially non-linear design allows you to decipher the language at your own pace through a variety of means, building up your repertoire to go deeper and deeper into the factory until you can finally make your escape.
