The Hill Top Zone boss features Robotnik in a submarine-like vehicle that emerges from the lava. The arena is a series of platforms above a lava pit.
Phases & Attacks:
- Lava Eruption: Robotnik's submarine will emerge from the lava, often causing small lava eruptions on the platforms.
- Laser Attack: He will fire a laser beam across the platforms.
Strategy:
- Hit Robotnik's Top: Robotnik is vulnerable on the top of his submarine when it emerges from the lava.
- Dodge Lava Eruptions: Watch for the small lava eruptions on the platforms and move to a safe spot.
- Dodge Laser: Jump over the laser beam when he fires it.
- Stay on Platforms: Falling into the lava is an instant death, so prioritize staying on the platforms.
This boss requires 8 hits. The key is to time your jumps to hit him as he emerges and to constantly be aware of the lava and his attacks. Patience is crucial.
