I wasn't sure what to put in for the mod version info. I am on 1.1B4 currently, but I don't know if it makes a difference with just a scenario and map file.

And sorry, I forgot to put a readme file in with it.
Copy the map file to your C:\Program Files\Stardock\TotalGaming\GalCiv2\Data\CustomMaps folder.
Copy the scenario file to your C:\Program Files\Stardock\TotalGaming\GalCiv2\Data\English\Scenarios folder.
Then select the 5 Way 1 Planet Each map in the Custom Map list, and the matching scenario, as you are starting a new game.
