custom project: forerunner extinction

this project (which is also my first) is a multi-player map called "forerunner extinction" the main building was the biggest part of the build, i tried to add some interesting features like flood spores, a roof top hide out and some forest area. you may notice in the pic 5&7, there are some clips with an empty space in between them. you can't see it in the picture bu there is water in those spaces.
