History

Sonic the Hedgehog (8-bit)

In the 8-bit version of Sonic the HedgehogDr. Robotnik used this vehicle to attack Sonic when he arrived at the end of Bridge Zone. In spite of Robotnik's efforts though, his vehicle got destroyed by Sonic in the end.

Battle

The Bridge Zone boss is the second boss of Sonic the Hedgehog. The player fights it at the end of Bridge Zone Act 3.

Boss guide

The Bridge Zone boss fight with Robotnik is significantly more difficult than the Green Hill Zone boss. Like in many other third Acts in the game, there are not any Rings when the player faces Dr. Robotnik in his submarine, which has two small turrets.

In the Master System version, Robotnik will lurk beneath the water between the islands, only to periodically pop up and fire projectile and then hide in the water again. The player has to duck and wait for a good moment to Spin Jump onto the submarine to damage it before it fires A good victory strategy is to stand in the center of screen and duck under the arcing projectiles, before landing a hit on Robotnik as he submerges.

The level layout of Bridge Zone Act 3 differs greatly between the Sega Master System and Game Gear version of the game. In the Master System, the fight occurs on small islands with bottomless waters between them, but in the Game Gear version, the islands are replaced with sloping bridges due the screen resolution of the Game Gear.

The layout of the Game Gear version's boss arena can cause difficulties in case the player attempts to duck beneath projectiles on the sloping bridges, only for the duck to turn into a unwanted Spin Attack, which often sends Sonic straight back into the path of the projectiles. On the other hand, when Robotnik appears in his submarine, the player can easily do the Spin Jump without worrying of falling off. In fact, there is an effective strategy: simply roll into Robotnik's submarine to deal about three hits of damage at once.

Once Robotnik has taken eight hits, he will be defeated and flee in his exploding Egg Mobile, allowing the player to open the metal cage and complete the Zone in doing so.
