To Install, first download Long War from Nexus and install it. Download and unzip Easy War. Drag the two files into the following folder:
�SteamLibrary\SteamApps\common\XCom-Enemy-Unknown\XEW\XComGame\Config
This will replace (or prompt you to replace) the files DefaultGameCore.ini and DefaultGameData.ini
Play long war and enjoy! This will only work on Normal Difficulty. Anything above that will get significantly harder.
