Play Sonic 3 Delta Online

Sonic 3 Delta is a fan modification of Sonic the Hedgehog 3 for the Sega Genesis, also known as the Mega Drive. It was originally developed and published by Sega. This version builds on the original 1994 release, a game that arrived late in the console's life and pushed its hardware with larger levels and a save feature.

You control Sonic, Tails, or Knuckles, each with unique abilities, as you run and jump through vibrant zones to stop Dr. Robotnik. The main objective is to collect the Chaos Emeralds by navigating special stages, which are accessed through giant rings hidden in the levels. Signature mechanics include the elemental shields that grant specific powers, like a fire dash or double jump, and the ability for Tails to fly or for Knuckles to glide and climb walls. The game moves at a breakneck pace, demanding quick reflexes to avoid traps and enemies, though it offers a more continuous, linked world compared to earlier entries. It feels like a polished, expanded version of a familiar race, where mastering your character's movement is the key to success.
