Map description:
Large city map with the orginal Sears Tower at the center of the map. The main building includes indoor areas. Lots of weapons and objects to throw. After playing the twin towers map I wanted to build a large city map. This map has nice look and feel of a city. Includes teleports, elevator lifts and push streams.
