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.
