Sand Ocean

Sand Ocean is the third stage in the Dark storyline of Sonic Adventure 2 and the second stage playable with Eggman. It represents Eggman's attempt to return to his Hidden Base hideout, after his confrontation with Knuckles and Rouge.

Appearance

The major gimmicks of this level are the pillars that can be knocked over by locking-on to the Dynamic packs attacked to it and an interesting concept of bottomless pit, since the level is constructed above sand where the Egg Mobile will sink into immediately if in contact, because the mecha is too heavy to sustain its weight above the surface. Since Sonic is lighter, he'll be able to escape the sand by repetitive jumping, as seen in the Egg Golem boss.

Other level specific-objects are GUN flags, torches and fire pots that will hurt if touched, black and yellow jars that can be smashed, GUN Gas Tanks that can be destroyed and then used to reach higher heights

On the goal platform, stand close to it. Rotate the camera to the left and Big is sitting on a platform, seemingly trying to fish in the sand.

• First checkpoint: In the platform where the first pillar that needs to be knocked and the second Chao box are.
• Second checkpoint: On top of a pillar, on the pillar platform area.

Lost Chao

Just before the second checkpoint, there's a gyratory platform, which will also take to a side hallway. Hover to the platform with a spring and then hover to the one moving back and forth. Destroy the steel containers, hover to this platform and the Chao is at the end of the next one.

Upgrade

Eggman's Mystic Melody upgrade can be found in this level - though it requires the Jet Engine to access. It’s in platform to the left of the first gyratory platform, right at the beginning.
