Roaming Romans infest a beautiful forest and sunken lake. Explore an intricate maze. If you're underwater, breathe the air bubbles to keep from drowning. A countdown begins when your oxygen's running out.
Aquatic Ruin Zone 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.
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, the player 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 to avoid the water altogether.
The ancient stone pillars that lie dotted around Aquatic Ruin are riddled with traps. Some will rise up when you approach and you must jump on them to destroy them. These can be dangerous in conjunction with the arrows fired out by other pillars, but otherwise they are not a threat.
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.
