Creator: Kell

Classification: Mod

Base Game: Sonic Adventure DX


This mod ports multiple Sonic Heroes content into Sonic Adventure DX game. The levels ported include Seaside Hill, Sea Gate, Ocean Palace, Road Rock, Grand Metropolis, Power Plant, Casino Park, Bingo Highway, Hang Castle, Mystic Mansion, and Egg Fleet along with their objects and some sounds. Egg Pawns, Falcons, and E-2000s are also added. Some variants of the egg pawns are added but not used yet. Characters include Sonic, Shadow, Amy, Espio, Tails, Rouge, Cream, and Charmy. The models and animations along with their original weight and structure are taken from the PC version of Sonic Heroes. Manual configuration is required to enable them as of now. If you wish for Lantern Engine to work with this mod, please use the version of Lantern Engine provided above, credited to SonicFreak94.

The mod utilizes SonicFreak94’s SADX DC Lighting for better lighting accuracy and vertex alpha transparency. It can work without it, but some areas may look odd. The levels Hang Castle and Mystic Mansion rely on this lighting mod.

You can also activate other mods such as Seaside Hill Night Version by Sewer56lol and Music Edits by Darkspines147.
It is compatible with mostly everything as long as you run it afterwards.
