This mod changes the score ranking system in "The Unleashed Project" to be more in line with what it originally was in Sonic Unleashed. That's right - this is a mod of a mod.
The original "Unleashed Project" mod for Sonic Generations features extremely difficult score ranks, which are much, much different from the way they were in Sonic Unleashed. To some people, such as myself, they are too difficult to complete. S-Ranks Unleashed attempts to translate/restore the original score ranking system from Sonic Unleashed back in to "The Unleashed Project" mod.
