You have to extend the map after the large observation window cover called "the_curtain" by adding whatever you want to have behind it. Change whatever you want in the existing section, as long as you keep the general layout.
Other rules:
The new area should not be accessble, i.e., this will be an observation point or whatever you make it. So basicly you have to build scenery in this compo.
Rules of the previous competition apply as well.
You have untill Friday 11th so GET YOUR ARSES MAPPING.
