Description, Sonic the Hedgehog (8-bit) manual[1]

Green Hill Zone (グリーンヒル Gurīn Hiru?, lit. "Green Hill") is the first Zone in Sonic the Hedgehog for the Master System and Game Gear. Located on South Island, Green Hill Zone is two full-length acts long with a third act containing a boss fight with Dr. Robotnik. Green Hill Zone is set across numerous hills and fields with underground caves.


Green Hill Zone, again like its 16-bit counterpart, is filled with rolling plains of green palmtrees, wooden totem poles and jauntily colored flowers. Tall mountains can be seen in the horizon, behind a blue lake. Like its 16-bit counterpart, all the Green Hill Zone's tile landmasses have checkerboard patterns. This Zone also exclusively include cavern sections with simple, brown wall tiles.


Green Hill Zone has several basic gimmicks, such as Springboards and floating platforms that are either stationary or move back and forth in different patterns. On tall hills, the player can also perform the Spin Attack to roll down hills at high speed and then be sent into mid-air by small ramps at the feet of the hills.


Act 1

Act 1 is a linear track without alternate pathways. After climbing a huge hill and obtaining the Invincibility, the player can roll down the hill slope and get sent into mid-air by a ramp. Picking up Power Sneakers nearby the ramp lets the player go through the Act even faster. There are also sections with wide pits of Spikes which the player has to cross using floating platforms.

Act 2

Setting itself apart from its 16-bit counterpart, Act 2 starts with the player falling into a cave complex that they must navigate to get out. It should be noted that a Shield can be found on the left side after falling in the cave. The lowest point of the cave is partly filled with low water and has Spikes on the ceiling. By using quick Spin Attacks, the player can defeat incoming Crabmeats. After finding the Arrow Monitor, the player then has to climb out of the cave complex. The player's next task is then to cross a pit using moving platform. Afterwards, the player can use Spin Attack to roll down a hill and get sent into mid-air, towards the end of the Act.


In Green Hill Zone Act 3, the player has to climb up a steep hill. Right from the start, there are few bottomless pits. However, the second pit is actually beneficial, holding an extra life at the bottom for the upcoming fight against Dr. Robotnik, who is encountered at the top of the hill.

The boss fight with Robotnik in his Egg Mobile is relatively simple. Right from the start, Robotnik will hover above the arena three times, out of the player's reach. Robotnik will then slowly descend to the surface, which is the only time where the player can hit him with the Spin Jump. Meanwhile, Robotnik prepares to charge into the player, before flying quickly across the arena and off-screen. He then repeats this pattern until the player defeats him.

In the Game Gear version, this boss fight is even easier, as Robotnik is left vulnerable to attacks at all times, even as he flies above the arena. Once Robotnik is defeated after taking eight hits, he will flee, allowing the player to open the Capsule and complete the Zone.

  • In Green Hill Zone Act 2, after the player comes across the Arrow Monitor and climb further to the exit point of the cave complex, they have to keep going further left and then drop down to the underground waterfall. Inside a hidden cave, a Chaos Emerald can be found lying on the right side.


  • After dropping down to the lowest point of Act 2, the player can move left and pass through invisible tunnel to find hidden room with extra life Video Monitor.
