Tool Bar/The Camps

Summary: At first, camps were very chaotic. Methods of murder were inefficient and technology took awhile to develop. Larger gas chamber were made to hold more people, more efficient gas was used, body fat was used as a fuel to burn other bodies faster, and bone-crusher machines were made. These were all ways to dispose of bodies.
