Another Shadow in Sonic 1 Ultra Ego Edition is a fan-made ROM hack of the original Sonic the Hedgehog for the Sega Genesis. This modification likely adds a new playable character, "Another Shadow", introducing new gameplay elements, altered level design, or modified abilities. The "Ultra Ego Edition" moniker may refer to a particular version of the hack with additional content or gameplay tweaks. Its distribution is likely through online fan communities and ROM-hosting websites. The visuals would retain the style of the original Sonic game with some modifications.
