You play as a human being who has waken up in a cryotank... you have no memories, but you find some messages from the past... from yourself...
You don't feel good... maybe this is a radioactive and toxic place ... you may not have much time... You find some stupid robots... with strange answers to your questions.
The gameplay is very simple. You can move, take items and use them. You can examine a lot of things. You can find information about the world and the story.
You must build up the story using these pieces of information. This is a very important and unique part of the game. So: explore, search, think.
