Aquatic Mine

Next stage >>

Aquatic Mine (水生鉱山 -suisei kōzan?) is the eighth stage of the Hero story in Sonic Adventure 2 and Sonic Adventure 2: Battle, and is playable as Knuckles the Echidna.

Description

The Aquatic Mine is an abandoned coal mine located in the vicinity of Pumpkin Hill. In keeping with the imagery developed in Knuckles' previous stage, many of the symbols found about the mine seem very Halloween-themed. This level is also infested with Boos, enough to the point that a warning sign has been posted. It appears that at some point during its operation, the mine flooded.

There is apparently a connection between the Aquatic Mine and the sewers of Central City, as Knuckles emerges from a manhole in said city and simply states that he must have "gotten lost in the mines."

Story

Knuckles discovers the Aquatic Mine in his search for the Master Emerald shards. After finding all the Emerald Shards however, Knuckles gets lost in the mines. Eventually, he ends up in the sewers of Central City, where he bumps into Sonic, Tails, and Amy, and joins them on their adventure.

Gameplay

There are three Ball Switches present in the level that affect the height of the water within the mine, with adjustments being necessary to reach the higher levels of the forlorn place.

Overview

1st Mission: Find 3 pieces of the Master Emerald!

2nd Mission: Collect 100 rings!

For some quick Rings, the player should collect all the ones around them at the start of the level, then go up to the top floor and hit the 10 Rings Item Box. The rest of the Rings can be found scattered throughout the level, with a notable amount placed on the path leading to the Air Necklace.

3rd Mission: Find the lost Chao!

From the beginning of the stage, the player should go up the center structure to reach the top floor and keep the water level at one. On the side where a 10 Rings Item Box and a Hint Box can be found, the player will find an Ancient Ruin behind a pile of wood. They must play the Mystic Melody on it, and then will see a door open. The player should go inside and Swim down, which will take them to the room where the Boos are. They must find the two skulls statues in the corner, then look for a shadow on the ground, or Rings up higher. Once the player finds these, they should take them up, which will lead them to a tunnel. The player must go to the end of the tunnel (there is an Extra Life behind the iron ball) and take the Pulley up, and the Chao can be found just ahead.

4th Mission: Collect the Emerald pieces in 3 minutes 30 seconds!

This mission is the same as the first, except with a time limit. The player must work quickly to find the missing Emerald Shards.

Last Mission: Clear Hard mode!

As with all treasure hunting stages in Sonic Adventure 2, the Emerald Shards are in three set locations, and are as follows:

  1. First, the player should head for the large wheel in the northeast corner of the main room, then stand on the edge of the southern plank and put the Sunglasses on. A Spring should appear beneath the player, which can launch them to a shard.
  2. With the water level at level one, the player must dive into the mineshaft along the western wall on the second floor and navigate the tunnels. There is only one route, so the player must keep going until they find the second Emerald Shard at the dead end. They should be careful of the final descent, which is littered with iron balls.
  3. The final Emerald Shard is near the lost Chao. Instead of taking the pulley, the player should look behind the iron ball.

Level Up Item

There is an optional Level Up Item available for Knuckles in Aquatic Mine called the Air Necklace. This allows him to stay submerged for any period of time without drowning. When returning to this level to complete further missions, this Level Up Item is very helpful.

Chao Container locations

  1. In the third Ball Switch room, the first Chao Container can be found in the left corner of the Ancient Ruin entrance wall, behind the stack of lumber.
  2. Go to the top floor and hit the third Ball Switch. Then, from the starting point, enter the mineshaft at the southern wall on the bottom floor, and the second Chao Container can be found near there.
  3. While the third Ball Switch is activated, stay on the top floor while the water gets sucked up. Go then past a caution sign with Boos on it, and keep going straight to find the third Chao Container on a ledge.

Animals

Big the Cat sighting

To the left of the Wide Spring, there is a mineshaft which has Big inside it. However, Big only appears inside the mineshaft when the water is set to the first or second level.
