Ancient Ruin



The Ancient Shrines are a number of small shrine-like temples located in every stage in Sonic Adventure 2. Its texture and design is based on Lost World, an Action Stage from Sonic Adventure.

At first, the characters can only examine the shrines (only Knuckles seems familiar with them). However, upon obtaining the Mystic Melody upgrade, they can use the music created from it to activate these shrines, and they will create a path that will lead to either short cuts through the level, other upgrades, or lost Chao.

How these paths open depends on the level such as:
 * Floating platforms appearing.
 * Large doors opening.
 * A portal opening above the shrine which can teleport the player.
 * A line of rings for light dashing along.
 * A spring appearing on top of or near the shrine.
