The installation is fairly simple, simply decompress (unzip) the main file, and copy and paste the folder inside it, labeled, "Manage" over the same file inside the Home Wars_data folder. It will ask you if you want to replace and overwrite, do so. There is an included back-up for the data, so you can switch between sand-box mode and the regular game with ease. For the file labeled, "Assembly-CSharp-backup" simply rename the "Assembly-CSharp.dll" file to whatever you like, and get rid of the "-backup" in the file name of "Assembly-CSharp-backup". This will return the game to normal. Have fun!
