So.

The Plot : 

Our characters are sent to this planet in a reality show for aliens.  All their movements are watched by billions of creatures from the universe. Of course our characters do not know this , they are simply teleported to this planet with no knowledge of where they are or what to do. In each region ( the 4 of the habitats )  there will be an artifact , when our characters will take all of them...they will be sent home ( maybe ) but our characters don't know that. In the first part of the RP will be centered on character interaction and survival on a hostile world. 

Dangers :

The first part of the RP will be focused on a man vs nature thing. On this planet , they are not alone. There are creatures on this planet. Hostile creatures , that will try to kill our characters ( if a character dies , the player can make a new character if he wants to do so ). 
The second part of the RP will be harder. Once one of our characters will find one of the artifacts , new creatures will introduced on the planet. Intelligent creatures that will hunt the players.
