Full release. Completely overwrites the original Rome II score with the music of Rome: Total War. Current issues include occasional stuttering on the Campaign Map when tracks change, and the culture variation feature is having trouble.
To install, first unzip the "music_rtw.rar". Inside this you will find an image and a pack file. The image will then show up in the Launcher Mod Manager to let you know exactly what you're playing! Place both the "music_rtw.pack" file and "music_rtw.png" image into the data folder of Rome II. This can be found in the following pathway:
"Program Files/Steam/SteamApps/common/Total War Rome II/data"
When you boot up the game, click on the "Mod Manager" Icon in the game launcher, and check the Music Mod box when it appears. If you have several mods installed you may have to navigate along till you find it.
