The archive contains 2 files: a data file and a data file_2. The first is the mod itself, and the second is needed in case you want to remove this mod and return everything as it was, that is, Ted will attack you again and will not be on your side. So, to install this mod, you need to copy the data file file to the Dead Rising 2\data folder with the file replacement. And then start the game, but to save the Body you will need to return to the mission in which he participated, and this is almost the beginning of the game. And to return everything as it was, rename the datafile_2 file to datafile and also copy it to the Dead Rising 2\data folder with the file replacement. Have a nice game!
