Hill Top Zone is the fifth Zone in Sonic the Hedgehog 2, featuring extended level blocks such as Star Light Zone's start loops and Green Hill Zone's spin tubes.

Overview

This mountainous stage features lava pits and underground caverns, similar to Marble Zone. However, Hill Top features no sturdy ruins of long-gone civilizations; they would have been ground to dust by the frequent earthquakes which ravage the Zone and fill the chthomic spaces with scorching magma—often while Sonic and Tails are inside. Outside, pine trees rise over a landscape of blue-tinted rocks, with rickety vine chairlifts connecting one peak to another. See-saws and loop-the-loops are scattered throughout the zone; while the latter springs our heroes up the mountainsides, the loops invariably send Sonic and Tails cannonballing into the volcanic caves. The boss at the end is Submarine Eggman.

Geographically, the Zone is located amidst the high peaks of West Side Island. It can actually be seen from Emerald Hill Zone; the vertiginous ridges of Hill Top's background glimpsed on the horizon at the far right of the first stage.

A slightly modified version of Hill Top Zone's art is also used in Emerald Hill Zone, with different coloration. No one knows why for sure, but Emerald Hill Zone and Hill Top Zone were developed during the same time which can be proven by playing the Nick Arcade prototype and Simon Wai prototype where they were both completed simultaneously.

Quotes

Lava boils from volcanoes and earthquakes shake the ground! Spring for the Rings on teeter-totters and blast through underground tunnels and caverns.

The thing that stands out most in this zone is probably the way the whole screen shakes in the areas where the lava is moving. And then the mountain in the background has a slightly polygon-like look to it. We were aiming for a look similar to the kind of thing we had in mind with Sonic 1's Green Hill Zone.

Sonic the Comic

In the Sonic the Comic series, Hill Top Zone first appeared in issue #20 where it was depicted as a barren landscape populated by a tribe of native birds who request Sonic and Tails' help. According to Chief Kordon, the Mountain of Destiny was about to erupt, prompting the heroes to go inside and investigate. Inside, the heroes were attacked by a Rexon, and Sonic transformed into Super Sonic under great pressure. Though they found the cause of the eruption, which was Dr. Robotnik's Seismatron, Super Sonic attempted to escape with intentions of taking out Tails, though the fox manages to use reverse psychology to get Super Sonic to run circles around the erupting lava, cooling it and forming a Sonic statue.

The Hill Top Zone would later face other threats, including a swarm of Badniks that invaded from the IceCap Zone via a portal, and a missile fired by D.R.A.T. which Sonic was able to divert using his speed.
