You are the nameless protagonist of the game. You are lost in a hostile environment with only one way to go, but you can't tell what will happen, you don't know what is in front of you, and you don't know how to get out of this place. All you know is that you have to move forward, you have to find a way to get out of this place.

To find this way, you need to explore the different parts of the level, find all the different items, and use them to help you reach the exit. But be aware, you only have one shot, and if you are killed, you will have to start over again.
