Berlin_1942 is a large 6 player map roughly based after the BF42 Berlin map for all you Battlefield 1942 fans.
I had to make a few changes to allow space for base building but I tried to keep the overall feel of the map intact.
It's best played with fixed positions.
The map is in .sga format so to install it simply put the .sga file in the maps folder located in your Company of Heroes (root) folder.( Default would be...C:\Program Files\THQ\Company of Heroes\Maps)
If there is no maps folder in your Company of Heroes (root) folder just create one and put the map in it.
Being that this is a .sga map you will also need Mannerheims CoH launcher which you put in C:\Program Files\THQ\Company of Heroes folder, then create a shortcut of the file to your desktop.
Once you have done all this your ready to play so invite a few friends and enjoy!
