Every single game of Mars has a particular topic in which you will create, answer, and debate questions related to it; eventually this is defined before starting the game. When you start playing, the topic of the game will appear, but you can also revise this by clicking on your avatar that is on the top left corner of your colony. In case there are any documents uploaded to the game, you can view them by clicking on the ‘Documentation’ icon on the bottom right corner.
