It is a completely free mod to please FNF fans. It was developed right before the official release of Week 7. It was specially created to add an Ugh song to the gameplay. This song appears for the first time in the series. Furthermore, the mod features a tankman who is the main antagonist of the 7th week. Thus, this add-on adds another unofficial week to the game and, of course, a new rival – the tankman. Try it to see if your sense of music is sharp enough to catch all notes correctly and win.
