Requires the V0.5 release to play, the V0.5.1 patch is not necessary as it is included in this download. Play through Act 4 of Planet Wisp from Sonic...
Similar to brianuuu's Tropical Resort All in One, this mod aims to give the same treatment to Planet Wisp, porting all 6 acts plus a 3D hub into Sonic Generations, staying as true to the original levels as possible with some added improvements to take advantage of the advantages Windows has over the Wii such as HD textures.
Act 4 is now available for everyone to play, as an addon to the previous release so that Acts 1 through 4 can be played in the same mod, and you won't need to reset your save file for it.
Like the other three acts, Act 4 has been accurately recreated using the Generations engine, complete with HD textures and varying ways to play with both Classic and Modern Sonic, with Modern boosting his way through with the Orange Rocket wisp and Classic Spin Dashing along with the Pink Spikes wisp.
