This unofficial project ports back most of Sonic Unleashed's day levels from the Xbox 360 version into Sonic Generations on PC. It also includes any improvements that are deemed as necessary to accomodate to the better control scheme, higher resolution graphics, and a much smoother framerate.
I love this
This is an awesome total conversion mod for Sonic Generations that gives it the day stages from Sonic Unleashed. Frankly, it'd deserve the 10 for just making these stages playable without slogging through the rest of that game (which pales in comparison). But this mod goes above and beyond with clever secrets, redone textures, and a generally absurdly high attention to detail. A must-play!
Speed running and all this beautiful scenery!
