How to Beat Act 2

Sonic: The final boss for Sonic is a two-stage battle against Dr. Robotnik. The first stage is the 'Giant Eggman Robo', a massive mech that walks across the screen, firing missiles and lasers. You need to hit its head when it's lowered, often after it attacks. Use the platforms to gain height and avoid its stomps. The second stage is the 'Death Egg Robot', a smaller, more agile mech that flies around. It has a vulnerable chest plate that opens after it performs certain attacks, such as its homing missile barrage. Time your Spin Attacks precisely to hit the chest and avoid its powerful punches. Defeating this robot concludes Sonic's story.
