— Description, Sonic the Hedgehog 2 (16-bit) United States instruction manual[1]

Aquatic Ruin Zone (アクアティックルーイン[2] Akuatikku Rūin?, lit. "Aquatic Ruin") is the third Zone in Sonic the Hedgehog 2. As with most other stages in this game, Aquatic Ruin Zone consists of two standard Acts with a boss fight at the end of Act 2.


Aquatic Ruin Zone is a crumbling, semi-submerged stonework ruin



This Zone sports a couple of main terrain features that make it unique compared to the others. Water, for one; the movement speed underwater is much slower, so be prepared. Like with the Mega Mack from Chemical Plant Zone, if the player stays underwater for too long, Sonic will eventually drown. To avoid drowning, stand near a small pile of Air Bubbles on the ground and wait for a big bubble to rise. There are also alternate paths on the surface to avoid the water altogether.

The ancient stone pillars that lie dotted around Aquatic Ruin will rise up when the playable characters approach them and they must jump on them to destroy them. Aside from the underwater sections, the other main obstacles are pillars with Dr. Robotnik's face embedded on them. Their eyes will flash red when the player approaches them and after passing them, they will fire an arrow that flies horizontally and are usually dangerous in large numbers.

The boss of Aquatic Ruin Zone.

The boss here has totem poles that rise up from the ground. Dr. Robotnik will then float above the poles and hit them in an alternating pattern with his hammer, causing the totems to fire an arrow. Once this arrow hits the other pole, you must jump on the arrow and hit the Egg Mobile.

Sonic the Comic

In the Sonic the Comic series and its spin-offs published by Fleetway Editions, Aquatic Ruin Zone is a Zone on Mobius. Originally, it was an outpost created by the Drakon Empire millennia ago that was eventually abandoned and sunk into the local bodies of water. In the present day, Sonic once came to this Zone on a mission where he ended up awakening and destroying a Sentinel. Tails would later come to this Zone to destroy the Spider-Moth.
