Sonic the Hedgehog 3

Introduction: Sonic the Hedgehog 3 is an official 1994 Sega Genesis / Mega Drive platformer developed by Sonic Team and Sega Technical Institute. It continues the story of Sonic the Hedgehog 2 on Angel Island and introduces Knuckles the Echidna as Sonic and Tails' new rival.

Gameplay & Mechanics: Sonic can be played alone or with Tails following him, while Tails can also be selected separately. Sonic retains the Spin Dash and gains the Insta-Shield. Three elemental shields add new abilities: the Flame Shield protects against fire and lets Sonic perform an air dash, the Bubble Shield allows repeated bouncing attacks and prevents drowning, and the Lightning Shield attracts nearby Rings and gives Sonic a second jump. Tails can fly and swim using his twin tails.

Key Features:

• Six main zones, generally divided into two Acts with seamless or story-driven transitions.
• Flame, Bubble, and Lightning Shields with distinct offensive, defensive, and movement abilities.
• Blue Sphere Special Stages for collecting the seven Chaos Emeralds.
• Battery-backed save system through Data Select.
• Separate two-player Competition Mode with specially designed courses.

Locking the cartridge onto Sonic & Knuckles creates the complete Sonic 3 & Knuckles campaign and expands the playable content further.
