Run, jump, homing-attack and spin-dash through the Lands Between as the real Sonic from your own Sonic Adventure DX.
Play Elden Ring as Sonic the Hedgehog — Sonic Adventure DX's Sonic, with his own model, textures, animations, sound effects and voice, read from your own copy of Sonic Adventure DX the first time you play. Nothing from either game is in the download.
What you get
Needs Elden Ring 2.7.1 and Sonic Adventure DX (Steam). Single player, offline: Mod Engine 2 starts Elden Ring with Easy Anti-Cheat off. Sonic Ring keeps its own save (ER0000.sr2), started as a copy of your save the first time; your normal save is never written.
Controls — Pad: A jump / homing attack, X or B spin dash, right stick camera, RB Torrent's whistle. Keyboard: WASD, Space jump, Left Shift spin dash, E interact.
Built on ER Mario by Delta (MIT): its Elden Ring collision, combat and character-posing engine. Sonic is SEGA's, Elden Ring is FromSoftware's; this is a free fan mod.
