Aquatic Ruin Zone
From Sonic Retro
Aquatic Ruin Zone
Aquatic Ruin Zone is the third zone in Sonic 2, and is the token underwater level of the game. Pieces of Roman ruins are dotted around this vast lake, and some of them have tendencies to rise out of the ground in front of you, break off the ceiling above you or sink into the water. There are also arrow launchers built into the pillars that will shoot arrows at you should you pass them.
In the Simon Wai prototype, this was actually the first level.
Instruction Manual Description
|| 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.
—Sonic 2 US Manual, p. 13
|| The top and bottom of this stage are built completely differently. The loops along the top are a bit different from normal. The water, also, had to have the transparency set exactly right. And then, there are so many places where the routes intersect! From Sonic 2 on, we took a patent in America.
- Grounder - Drill enemy, hides behind walls and appears when Sonic approaches.
- Whisp - Fly enemy, attacks in swarms.
- Chop Chop - Piranha enemy, moves around slowly underwater.
