- 40When you reach the Starpost, go past it and hop across the platforms.
- 41When the screen stops scrolling to the right, go back to the first platform to find a Flame Shield nearby. Collect the Flame Shield. It'll make the Boss Battle coming up much easier.
- 42Position Sonic on a platform and wait for it to descend.
- 43When you reach the waterfall of lava at the bottom, Robotnik will emerge from the lava on the right side of the screen.
Boss Battle: Dr. Robotnik's Mine Launcher Machine - 14 Hits
Tips
- The mini-boss before the Act 2 boss involves a Hand Machine and two wheels that fire projectiles. Each wheel takes 4 hits to destroy and can be a nuisance.
- The Hand Machine copies your movements and tries to pound the ground; keep running back and forth to dodge it and hit it once when it pounds.
- Collect the Flame Shield before the boss battle to make it easier.
- During the boss battle, Robotnik fires eight missiles; hop across platforms to dodge them.
- The collapsing ledges section after meeting Knuckles requires careful timing to avoid falling.
