Sonic, Shadow, & Metal Sonic Gameplay Overhaul

Creator: Benji along with many others

Classification: Mod

Base Game: Sonic Adventure DX

Creator's Description

This mod introduces a much bigger to come mod for SADX, where I plan on adding tens of levels and even write a story and everything. So far I’ve finished entirely Sonic, Shadow and Metal Sonic’s gameplays (well, except for Neo Metal Sonic that is not done yet, but almost). So the mod only lets you play as Sonic, Shadow, and Metal Sonic. You can also swap characters mid-level.

Creator's Recommendations & How to Install

You’ll need the following mods to be active for my mod to work properly :

  1. Disable Upgrades Models by MainMemory
  2. XInput by SonicFreak94
  3. DirectX 11 by SonicFreak94

I also greatly advise to use the following mod for better experience :

  1. Expert Mode by UncreativeUserName

Download link of these 4 mods:


  1. Download SADX Mod Loader
  2. Install SADX Mod Loader
  3. Unpack the contents of the zip archives to the “mods” folder. (You should end up with the 5 mods in there)
  4. Enable the mods in the Mod Manager.
  5. Make sure “Scale HUD” is unchecked in the Mod Manager to avoid giant HUD when pausing the game
  6. Using the “Configure” button in the Mod Manager, set “OIT_no_text” mod’s “Maximum fragment count” to 32. (Try lowering this value if you experience lag)
  7. You must load my mod LAST or else issues will happen, like the Chaos Spear not working or textures problems.
  8. You shouldn’t play any other mods but these 4 to avoid eventual bugs

Controls & Gameplay

Swapping Characters

  1. XBOX360 controller : Press LB+BACK for Sonic, LB+D-Up for Shadow, LB+Down for Metal Sonic.

  2. Dualshock Controller: Replace LB with L1.

  3. NOTE: You can only swap when on ground or jumping, and when not in Super/Hyper Form.


Destroying enemies fills the energy gauge (upper gauge) while rings fill the level gauge (lower gauge). The upper one is necessary to use special actions (RB-buttons actions (R1 on dualshock)).

The lower one increases the special actions effects.

  1. LV1 : Special actions cost less
  2. LV2 : Special actions cost less + they are enhanced
  3. LV3 : All of the above + your upper gauge gets slowly filled with time and rings
  4. Press B to activate the level gauge.

Known Issues/Bugs

  2. There’s sometimes random crashes. One cause has been identified though: DOn’t use Chaos Spear in Twinkle Park Act 1.
  3. Don’t try Pinball Tables; they are broken.
  4. Don’t go to Chao World. It crashes.
  5. Metal Sonic can’t get on the snowboard in Ice Cap Act 3 for some currently unknown reason. You can restart and use it normally.
  6. Sometimes Shadow loses all his momentum when punching. This happens especially in Speed Highway.
  7. Cop Speeders (the sort of flying monkey cars in Speed Highway) do weird things but it was like that originally. It just doesn’t mix well with my mod.
