Boss Battle: Dr. Robotnik's Mine Launcher Machine
This boss requires 14 hits to defeat.
Tips
- Collecting the Flame Shield before the boss battle will make it much easier.
- The two wheels that appear initially fire small projectiles; run back and forth to dodge them. Each wheel takes 4 hits to destroy.
- The Hand Machine mini-boss copies your movements and attempts to pound the ground; keep running back and forth to dodge it, and hit it once when it pounds.
- When Robotnik fires eight missiles, hop across the platforms to dodge them.
- During the scrolling section with collapsing ledges, move carefully to avoid falling.
