Fifth level, Sonic the Hedgehog 2 |
Number of Acts: 2 |
Boss: Hill Top Zone Boss |
Hill Top Zone is the fifth zone in Sonic the Hedgehog 2. It uses the same graphics from Emerald Hill Zone. No one knows for sure why they had this zone clone.
Hill Top Zone has extended level blocks, such as Star Light Zone start loops, and Green Hill Zone spin tubes.
The zone also contains lava, and has caverns where you can be trapped during earthquakes (due to a layer of ground moving up and down). Before the boss in Act 2, there is a room full of rising lava and platforms to the exit at the top. This is commonly known as the "volcano."

Instruction Manual Description
Lava boils from volcanoes and earthquakes shake the ground. Spring for the rings on teeter-totters and blast through underground tunnels and caverns.
Enemies
- Rexon - Plesiosaur enemy, sits in lava and throws fireballs at you. Once destroyed, its body can be used as a platform to stand on.
- Spiker - Cone enemy, launches its cone at you when you jump over it.
- Sol - Spherical enemy, surrounded by 4 fireballs which it throws at you. Referred to as "Sol" in the instruction manual, and "Ghora" in Sonic Jam.
Prototype Differences
Early Prototype/Nick Arcade Beta
- Lava doesn't cause harm
- Green orbs are used as the weight on teeter-totters instead of a Sol without fireballs
- Cable lifts do not work properly
- Due to screen limits not being fixed from Sonic 1, Act 1 cannot be completed normally.
- The collision array in Act 2 is missing
- When the earthquake is triggered in Act 2, the game crashes. This is because the leftover code from Sonic 1 calls for the event between Acts 2 and 3 of Scrap Brain Zone, but the data is not there.
Wai Beta
- Sonic doesn't spin when going through tunnels.
- There is no earthquake sound effect.
