Team Brick to Brick is a small, urban style, Bagman Map by Sonik.
The map has great texturing and lighting. It's a mirrored map with the two bases inside old industrial stlye buildings and two money drops in the centre of the map.
There are plenty of weapons and other items and you'll only need about six people to have a great time playing this map :)
Just unzip the files to your Kingpin folder and they will be placed in the correct locations.
This is currently the most popular map in the Bagman servers.
