Installation
========
1. Requires a 1.08c installation of Capitalism II.
2. Take a copy of your old Cap2.exe for safe keeping as the mod overwrites the existing one.
3. Replace the Cap2.exe in your Capitalism II directory with the new one from the download and make sure it overwrites it.
Multiplayer
========
All players must have the same Cap2 executable or the game will de-synchronize fairly quickly.
