The berlin_under_siege.zip file you have requested: Maps / Conquest / Berlin Under Siege - 5.16mb is not available. Perhaps try browsing all files for the game Battlefield 1942 and upload any files you want to share or are missing. This is the only information we could locate:
This file is a replacement for Jungle Berlin. This map has all kinds of new goodies and secret areas for you to explore. Don't assume what you see is all of it. Look around and you will find a whole new area! This map is not 100% jungle. In fact, it's 50% jungle now. I have added a whole new section to the map, changed the sky, changed the ground, and most of all, extended the map area.
You can download the DC version [file="15019"]here[/file].
