Basic. No god-mod, etc. 
It's GM Hosted so I will basically be controlling a lot of what will be going on so there will be no god-mods. Your dice rolls will determine what your next action will be. Say you get a 10d, you have about 4-5 options listed. Depending on what you roll on is what you will be doing on the maps. Anywhere else like in the ship which won't be the map, you can have free roam. 
There is a two paragraph minimum unless it calls for one.
